It calls the DASSL implementation of the BDF integrator setup routine D02MWF and the banded matrix setup routine D02NPF (if required), and, if the integration needs to proceed, calls D02MCF before continuing the integration. 0, length_thr=0. alioth. For example, with atol=1e-15, species with mole fraction less than 1×10 −15 are ignored in the output frequency determination. 000001, 1. testing. 3 fixed variable labelling function [tout,yout,dydu_out,varargout] = sens_sys(odefile,tspan,y0,options,Uc,vecpar,initfile,varargin) % % SENS_SYS is an extension of the ODE15s (v 5. isclose() for comparing fterms (Default value is 1e-8). values ()]) values2 = sorted ([data. rtol float, optional. get (attr, default) for data in datasets1. One way to deal with this problem is to assert that two floating-point numbers are equal to within some appropriate tolerance:: >>> abs((0. 001, include_improper=True) [source] ¶ Test to see if tensor is a valid rotation matrix, performs a test to check whether the inverse is equal to the transpose and if the determinant is equal to one within the specified tolerance. 001) ¶ Like assertAllClose, but also suitable for comparing fp16 arrays. The routine modifies this to take into account the relative precision of doubles. rtol (float, optional) – The relative tolerance to use in numpy. Sometimes programs are (foolishly) written using only one tolerance, e. b: the actual numpy ndarray or anything can be converted to one. 78 to about 0. This binning finds equally spaced quantiles. Not every function has to be documented, but you should be able to summarize any function you write in a clear, concise, docstring. If the true result is K_true, then the returned result K_ret satisfies abs(K_true-K_ret) < atol + rtol * K_ret The default is zero (i. The Formex class represents geometry as a simple 3-dim Coords array. 3 returns false. . b and the absolute tolerance. 0. eigh (mat, atol=1e-13, rtol=None, is_positive_definite=False) [source] ¶ Wrapper for numpy. knaw. python. assert_allclose. The FMU model is meant to be used for simulation purposes only. but it is not useful to me, circles should not divide the line as equal parts, i should be divide as required parts on selected line. Originally I have optimised a model with real data and got a set of parameters. Its is easily solved analytically: To use ode, one should put this equation in a system of two first order differential equations: It is important to note that FISPACT-II uses the iterative stiff-ode solver LSODES. problems with loop. For real or complex floating-point values, if an atol > 0 is not specified, rtol defaults to the square root of eps of the type of x or y, whichever is bigger rtol (float, optional) – Relative tolerance, defaults to 1e-7. e. Follow this link for a detailed description of the options. 182983512924 0. They are extracted from open source Python projects. isclose (a, b, rtol=None, atol=0. The default atol is zero and the default rtol depends on the types of x and y. When preprocessing the functions, the solver should split them into two lists: * self. Can you elaborate on what this test is doing? Can you produce a testcase that causes it without importing tensorflow? numpy. extremefill 0. isclose() for comparing fterms (Default value is 0. Default tolerances for the solver give good accuracy for the numbers of atoms of the major constituents of the inventory, but may give poor results for minor constituents. ) splipy. cgi?id=15523 Change-Id: I56f5801df8467cd0b3524143496b889170024a7b remove_degenerated_faces (rtol=1e-05) [source] ¶ Removes tiny triangles from the mesh. numpy.

Normally, this numpy. 6. deSolve provides R interfaces to solvers for stiff and non-stiff systems, and can take system descriptions in R, or as defined in dynamically loaded compiled code. Source code for numpy. 0**-50 for IEEE-754 double precision floats as used by Python. From this numerical problems would definitely not be a surprise. test_depthwise_c… allclose(a, b, rtol=1e-05, atol=1e-08) Returns True if two arrays are element-wise equal within a tolerance. ) Solving initial value problems for stiff or non-stiff systems of first-order ordinary differential equations (ODEs). test plugin to facilitate the generation and comparison of data arrays produced during tests, in particular in cases where the arrays are too large to conveniently hard-code them in the tests (e. Because the relative tolerance is only calculated w. This is a py. Args: mat: Matrix to take eigendecomposition of. 0)) Software carpentry: Python tools Pietro Berkes, Sept 2014 numpy. Thus, this example should be run with 4 MPI ranks (or change iproc). Fixed for all variables: vector of rtol i: custom relative tolerance for each system variable. Odepack A Python wrapper of the LSODA FORTRAN subroutine from ODEPACK. Then, it runs the fixtures in parallel by passing the each element of dtypes to the named argument. 0. solve() documentation. This function is essentially a copy of the numpy. times at which explicit estimates for y are desired. 8506 0. These values are set with the options 'ksp_atol' for the absolute tolerance, 'ksp_rtol' for the relative tolerance, and 'ksp_divtol' for the divergence tolerance. all_equal but use the arguments atol=1E-14, rtol=1E-12, and then again with atol=1E-15, rtol=1E-13. 0] b = [1. cgi?id=15523 Change-Id: I56f5801df8467cd0b3524143496b889170024a7b physt. When there is an option of either using forward or reverse mode directional derivatives, the condition ad_weight*nf<=(1-ad_weight)*na is used where nf and na are estimates of the number of forward/reverse mode directional derivatives needed. It's definition of tol as relative tolerance is also confusing (call it rel_tol or rtol or reltol). 793 0. dtol - the divergence tolerance 528: (amount residual can increase before KSPDefaultConverged() 529: concludes that the method is diverging) 530: - maxits - maximum number of iterations to use 532: Options Database Keys: 533: + -ksp_atol <atol> - Sets atol 534: . 4 06feb2018 NJGW * * 1. foo <- 1e-20 log1p(foo) This will make the largest term in the sum equal to *! survwgt 1. not much difference, but. linalg import svd def nullspace(A, atol=1e-13, rtol=0): """Compute an approximate basis for the nullspace of A.

The general principles and program steps are first explained and then followed by a series of examples with progressive complexity with respect to Python constructs and numerical methods. . 7277 0. Generates tracks with termination criteria defined by a delta function and it has similarities with FACT algorithm and Basser’s method but uses trilinear not yet verified for case with scale not equal to 1. 2. util. A FIXED joint adds equations to your system that aren’t necessary when two or more parts can be combined or merged into a single part. the compiled version is slower! The default atol is zero and the default rtol depends on the types of x and y. Petzold and Alan C. Subsequent calls within an iteration do not update the best value, so it’s not triggered. brentq, which is what this method uses underneath. The relative difference (rtol * abs(arr2)) and the absolute difference atol are added together to compare against the absolute difference between arr1 and arr2. This package was initially written for numarray by Paul F. isclose(a, b, rtol=1e-05, atol=1e-08, equal_nan=False) Returns a boolean array where two arrays are element-wise equal within a tolerance. More information… numpy. finfo(float). Absolute tolerance value is set to rtol/100. rtol (float) – The relative tolerance parameter (see Notes). Returns: y – Returns True if the two arrays are equal within the given tolerance; False otherwise. While we have thought of using assert_allclose instead of a == comparison, it tells us that the result is not equal to tolerance rtol=1e-07, atol=0. If xdot0 is given in the initial argument it may be either a compatible derivative satisfying g(t,x0,xdot0)=0 or an approximate value. The R function lsoda provides an interface to the FORTRAN ODE solver of the same name, written by Linda R. cirq. ndarray, *, rtol: float = 1e In particular, the tolerance is reduced to 1e-3 if at least one of the arguments is of type float16. ndarray, desired: numpy. deSolve is a collection of solvers, mostly from the 'lsode' family of solvers. The only problem is, it returns True if given a two-dimensional matrix and a three-dimensional One wants to test if a point on a circle, identified by an angle in degrees, is close to the point identified by the angle 0. 2, digits=2) == round(0. isclose easily enough. 382754789138 0. Is it safe to compare two float values if they have been rounded to the same number of digits? For example, round(0. For example, 0. debian. zeros should return same value. There was much discussion about this at one time. 192092896e-07) but now we use a much stricter tolerance (DBL_EPSILON=2. In the latter case %DAEOPTIONS(7) must be set to 1. #!/usr/bin/env python # ===== # MODULE DOCSTRING # ===== """ General utility functions for the repo. In particular, the tolerance is reduced to 1e-3 if at least one of the arguments is of type float16. However the main stopping criteria is the tolerance 1e-02 for p, 1e-03 for U . Linux software RAID (Linux kernel's md driver) also supports creation of standard RAID 0, 1, 4, 5, and 6 configurations.

Allows for optional consideration of periodic boundary conditions. np. where you can specify a tolerance for 'what is close' enough. Return True if all The requested task has been completed, but it is estimated that a small change in rtol and atol is unlikely to produce any change in the computed solution. fill_value : boolean, optional numpy. net> Date: Sun 27 Aug 2006 - 01:53:21 EST. rtol=1e-07, atol=0) distarray. 2. ctx_list objective non-zeros range from 1e-7 through 1e4 matrix non-zeros range from 1e-3 through 1e6 right-hand side non-zeros range from 1e-4 through 1e7 So the difference is up to 11 orders of magnitude. zeros(1, numpy. 7 (this has not been tested yet!) • Dummy parts should be massless; 0. Not expected: 392. This subroutine automatically shifts between stiff (BDF) and nonstiff (Adams) methods, such that the user does not need to determine whether the problem is stiff or not (as is the case when using the LSODE subroutine and class Lsode). This value is equal to 2. If y has a name attribute, the names will be used to label the output matrix. spatial from Orange. soetaert@nioo. assert_allclose_up_to_global_phase¶ cirq. sign(x) + 1) However, this code's behavior is slightly different from MATLAB. 3 Round to a Given Number of Decimals The NonlinearEigen has not been documented. tol = 2 means twice the usual tolerance; tol = 0.

An object of type Model groups multiple information that make it useful for a state or parameter estimation algorithm. 5623145, then the computed value should lie within the range of (1. You have to specify an absolute tolerance if you want to compare to 0. the compiled version is slower! If there is a time beyond which integration should not proceed (perhaps because of a singularity), that should be provided in tcrit. atol float, optional. Hello Sir Thank you very much for response. tools. assert_allclose(x, [1, 2, 3])). solvers. The performance benefits can be substantial (factor of more than 10) for problems in which all states vary slowly for long periods of time between fast spikes. def numerical_multiedge_match (attr, default, rtol = 1. Storti et. floatcmp. Absolute tolerance or atol is awkward to use when you have numbers with physical units. You can also set the absolute and relative tolerances atol and rtol , respectively, either as single values for all dependent variables or individual values class CallableDict (collections. 2204460492503131e-016) because the Base::Vector3d internally uses double, too. Hi Sergio, This test failure is benign. ma : a package to handle missing or invalid values. Your function NLL() looks for "new" in the environment in which NLL() was defined, but you generate your simulated datasets in a different environment (local to sim. Notes This Page's Entity. core""" numpy. Now, if the state changes from 0 to 1 and reltol is set at 1e-4, then abstolinitializes at 1e-7 and by the end of the simulation reaches a value of 1e-4. 0), **kwargs) ¶ Binning schema based on quantile ranges.

If xdot0 is not given in the initial argument, the dae function tries to compute it solving g(t,x0,xdot0)=0. hini : initial step size to be attempted; if 0, the initial step size is set to 1e-6, but it may be better to set it equal to rtol. r. If ``shift`` is an integer, the shift happens along axis 0. I understand that there is an isapprox function to deal with this. cupy. If the computed initial value for the absolute tolerance is not suitable, you can determine an appropriate value yourself. # Python code: calculating null space import numpy as np from numpy. 5. It is Exception class when it is not possible to distribute the processes over the number of dimensions. the second comparison also returns false with v0.

(Only applies when you are not operating in one step mode, that is when ITASK ≠ 2 or 5. c this name must be declared external in calling program. This should lead to all bins having roughly the same frequencies. This option is useful for handling the periodicity of crystals. blogger. , 2 processors along x, and 2 processors along y). eigh. linalg. Write a NumPy program to test if two arrays are element-wise equal within a tolerance. I installed caffe with anaconda, and I have the following directories under Just FYI, I submitted the same issue via bug reporting system(#2444148). atol: Value below which eigenvalues (and corresponding eigenvectors) are truncated. Allows to specify a relative tolerance rtol, which behaves as in numpy. inp (i. MPI4PY and DDM, by M. 4651 not equal to max(ph [, 1]) Mean relative difference: 0. 2 Heavyside Function. 7408 0. The content contained on this page includes the typical automatic documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users. Make sure you tune the rtol and atol values accordingly. For isapprox to work reasonably over pairs that may be very close, close, far or very far from each other , it is necessary to combine both the absolute difference and the relative inexactness and that is usually done additively. ops. Before the constant Double. We are migrating to a purely numeric versioning system in order to adhere more closely to software development best practices. rtol: Relative tolerance. atol : Absolute tolerance The absolute difference is equal to `atol`. To learn more, you can either read on below or browse some of the files in quantecon/tests/ and learn from these examples. Relative tolerance. That’s a small enough tolerance that I’m confident the numbers are quite close, but large enough to let floating point noise go through. 1' About. scilab. Solver-specific pre-processing. 18-4 Severity: serious Tags: stretch sid User: debian-qa@lists. I understood that in its true sense while developing the next version of Point (this time I'm actually foolproofing my code). This function is equivalent to allclose except that masked values are treated as equal (default) or unequal, depending on the masked_equal argument. Next StepsThis particular function is useful in testing if an array matches a known solution, allowing for a degree of tolerance through the rtol= relative tolerance or atol= absolute tolerance keyword arguments. "In the beginner's mind there are many possibilities in the expert's there are few. * `self. If either array contains NaN, then False is returned. 9205668. 0001, verbose=None, offset=None) ¶ The class Model represents an extension of an FMU model. EuDX (a, ind, seeds, odf_vertices, a_low=0.

Parameters In particular, the tolerance is reduced to 1e-3 if at least one of the arguments is of type float16. 0258 not equal to min(ph [, 1]) Mean relative difference: 0. Computes eigendecomposition of a Hermitian matrix/array. 0 because there is no tolerance by default. optimize. 1+0. In the past the tolerance was much higher (FLT_EPSILON=1. 562288876855, 1. (54 replies) I was recently reviewing a lot of the Python 2. freeviz. c t = the initial value of the independent variable. assert_allclose takes atol and rtol arguments for specifying the absolute and relative tolerance of the comparison. The species with mole fractions less than atol is not considered for the output frequency control. Notes-----When preprocessing the functions, the solver should split them into two lists: * `self. Output of SEDfitter tests on 22 Dec. This is useful for testing serialization methods on Python 3 that return saved strings as bytes. 562340123145) else the test will fail. I would stick to specifying rtol only. 4 fixed -modify- option in (typical) case where by variable doesn't index -touse- categories * 1. 5 * (numpy. Output: Note that iproc is set to . MPI for Python and the Domain Decomposition Method 1. times . 2763505. 2 == 0. 0001, atol=0. v1. Model (fmu_file=None, result_handler=None, solver=None, atol=1e-06, rtol=0. Once solutin converged, record stress, void ratio, saturation profiles. The tolerance values are positive, typically very small numbers. Decorated test fixture is required to return the arrays whose values are close between numpy case and cupy case. b, this test is asymmetric and you can think of b as the reference value. projection import LinearProjector, DomainProjection __all__ = ["FreeViz"] class FreeVizModel (DomainProjection): var_prefix = "freeviz" numpy. data[results['n_on']. a = [1. The test I proposed above is valid, or at least I think so, for any positive value of @xmengli999. A new mesh selection strategy with stiffness detection for explicit Runge–Kutta methods with very small tolerance rtol = atol = 10-13. The relative difference (rtol * abs(b)) and the absolute difference atol are added together to compare against the absolute difference Package ‘deTestSet’ February 15, 2013 Version 1. al. 2) - 0. I am limited to osx and ubuntu,but the package should be os independent, right? In the osx I tried python setup. Sometimes, the values we are interested in are not accessible at the exact point where the exception was raised. 0000000000000001e-05, atol=1e-08) [source] ¶ Returns True if two arrays are element-wise equal within a tolerance.

The keyword argument nans determines whether or not NaN values are considered equal (defaults to false). 0). MATLAB's heaviside function in python. (Only applies when you are not operating in one step mode, that is when itask ≠ 2 or 5. Numerically integrate unit weight profile to with sig at z=0 equals q0 to give new stress profile. i looked a little further into this, and the discrepancy between my laptop and the cluster seems not to have to do with python, per se, but with the C code used in certain areas of scipy. It gets complex number comparison wrong. 0, total_weight=0. only an ATOL. It is also possible to combine "near" and "offset" layouts (but not "far" and "offset"). 1540081. Not expected: 1. Proceed with caution. org>. 058 by setting "CatchMachineUnderflow" -> False option on my laptop. Advances in Parallel Computing for Computational Mechanics. That means they should not be longer than a single screen. the initial (state) values for the ODE system. c tout = first point where output is The model will stop if the ratio between the best moving average and reference moving average is more or equal 1-1e-3 (the misclassification is the less the better metric, for the more the better metrics the ratio have to be less or equal 1+1e-3 to stop). Possible fix (Discussed with @beam2d ) All builtin triggers, not only BestValueTrigger, are not assumed to be used multiple times in an iteration. zeros and cupy. The Hilbert's method to find coefficients of the minimum phase finite impulse response relies on Fourier transform from numpy. 126459538933 -- -- 0. utils. noise_processes=0: Number of distinct white-noise processes in the equation. assert_allclose (actual, desired, rtol=1e-07, atol=0, err_msg='', verbose=True) [source] ¶ Raises an AssertionError if (1) and (2) is a problem with ctypes. isclose (a, b, rtol=1e-05, atol=1e-08, equal_nan=False) [source] ¶ Returns a boolean array where two arrays are element-wise equal within a tolerance. assert_allclose¶ cupy. 0000000000000001e-05, atol=1e-08, equal_nan=False) [source] ¶ Returns a boolean array where two arrays are element-wise equal within a tolerance. Lyapunov Exponents The Lyapunov exponent of a dynamical system is one measure of how chaotic a system is.

Enormous torques may develop due to large Advances in Parallel Computing for Computational Mechanics. Not a scipy problem. Returns: Return type: bool. Defaults to zero. corresponds for k > 0 and α 2 < k (damping or amplification factor not too high) to a pure oscillator when α = 0, a damped oscillator when α > 0 and to an amplified oscillator for α < 0. org> Subject [GitHub] lebeg opened a new pull request #12441: Revert "fixed flaky test issue for test_operator_gpu. Suzuki The Analytic Garden http://www. isclose(a, b, rtol=1e-05, atol=1e-08, equal_nan=False) この isclose は単純に2点の距離を測って基準であるtoleranceよりも小さかったら True を返すというわけではなさそうである。 Release 0. NET Framework, most people know it is not safe to do double value comparison using the equal logical operator directly, as == in C# for example, and we have to compare the absolute differece between the two double values with a tolerance to see whether they can be thought as equal or not. 0) [source] ¶ Computes an interpolation for a parametric curve up to a specified tolerance. 2 KB checked in by jjr8, 7 years ago (); Incremented build number Added support for Python 2. Bitwise identity of NetCDF data — hashing numpy arrays July 10, 2013 — by Jan-Philip Gehrcke In a molecular dynamics (MD) simulation, a molecular system is evolved over time, i. allclose function. (What would happen if ATOL = 0 and True Value = 0? Would the convergence test ever be satisfied?) You should write your programs to take both RTOL and ATOL as inputs. atol (float) – The absolute tolerance parameter (see Notes). def pre (self, functions, x0): """ Solver-specific pre-processing. デフォルトだと値が設定されているのだけど、 relative tolerance というパラメターである。 numpy. utils. allclose(a, b, rtol=1. values ()]) return allclose deSolve is a collection of solvers, mostly from the 'lsode' family of solvers. First, the distance on the circumference D(0,theta) is equal to D(0,-theta), hence we can compare the absolute values of the angles. non_smooth_funs, for functions involved proximal steps. non_smooth_funs`, for functions involved proximal steps. Stat 3701 Lecture Notes: Computer Arithmetic 0. All dimensions that do not have a corresponding shift value in ``shift`` are left untouched (ie ``shift=(1, 0, 0)`` is equal to ``shift=(1,)``, with the exception that the former will trigger an ``IndexError`` if ``a. formel¶. Args: a: the expected numpy ndarray or anything can be converted to one. 04. Currently all assertion methods are provided by converting the tensors to numpy arrays and feeding them into an appropriate `numpy. allclose (a, b, masked_equal=True, rtol=1e-05, atol=1e-08) [source] ¶ Returns True if two arrays are element-wise equal within a tolerance. GEOS-Chem v11-02-final will also carry the designation GEOS-Chem 12. 0585601591978 --], mask = [False True The following are 50 code examples for showing how to use numpy. quantile_binning (data=None, bins=10, qrange=(0. 1 release candidate 1. Physical equations and useful formulas as quadrature of vector functions, viscosity, compressibility of water, scatteringLengthDensityCalc or sedimentationProfile. allclose(x, y, rtol=1e-05, atol=1e-08): returns True if two arrays are element-wise equal within a tolerance; rtol is relative difference, atol is absolute difference I generally agree with you, but this PEP needs some serious TLC. Lsoda(f, **kwargs) [source] ¶. Clone via HTTPS Clone with Git or checkout with SVN using the repository’s web address. Giving very low values for rtol and atol will likely make the test very flaky. This methods seems to be buggy. 4 code I have written, and I've noticed one thing: thanks to the attrgetter and itemgetter functions in module operator, I've been using (or been tempted to use) far fewer lambdas, particularly but not exclusively in key= arguments to sort and sorted. odespy. Christoph Gohlke recently started providing scikit-fmm binaries: results['significance']. The requested task has been completed, but it is estimated that a small change in RTOL and ATOL is unlikely to produce any change in the computed solution. 0 Title Testset for differential equations Author Karline Soetaert <k. values ()]) return allclose For example, if rtol is 1e-5 and atol is 1e-5 and the expected value is 1. Bases: odespy. 1 + 0. If units are attached, they must be consistent with the units of actual and desired. py build, and here is the output of it: # Torch Testing A collection of assertion methods to compare PyTorch Tensors in tests. assert_within(tensor, min_val, max_val, rtol=0) Ensures that all values of the given tensor are greater than or equal to min_val and less than or equal to max_val. In the examples above, k is the number of drives, while n#, f#, and o# are parameters to the mdadm's --layout option. RAID 1E numpy. curve_factory. allclose(a, b, masked_equal=True, rtol=1e-05, atol=1e-08) [source] Returns True if two arrays are element-wise equal within a tolerance. isclose(a, b, rtol=1e-05, atol=1e-08, equal_nan=False) A little disclaimer though: installing NumPy can be a non-trivial experience depending on your platform. u = parabolic(___,rtol) and u = parabolic(___,rtol,atol), for any of the previous input arguments, modify the solution process by passing to the ODE solver a relative tolerance rtol, and optionally an absolute tolerance atol. solve` documentation. Note: The tolerance values are positive, typically very small numbers. 945: to 0 which means ``rtol`` is not used. I think Anaconda comes with minGW so you could try to build scikit-fmm from source. rtol : Relative tolerance The relative difference is equal to `rtol` * `b`. An outline of a typical calling program for D02NEF is given below. 1, the timing reduces from about 0. testing` method. 14 i. I see nothing here that points to a numpy bug right now - the entire relevent stack trace is within tensorflow code. The relative difference (rtol * abs(b)) and the absolute difference atol are added together to 4. assert_allclose on l0 and l1. 2 2 in solver. Use Gs, e, Sr to calc unit weight (gamma) profile. 0 (or unassigned), not 1e-20. Specify the desired relative and absolute tolerance of the result. If not equal then iterate. It’s better to provide a general fix. This may be one of the reasons why CPLEX struggles. Solid arrows point from a file to a file which it depends on. 7728 0. 0%) x: array( Arguments y . Revision 1025, 221. A file is dependent upon another if the latter must be compiled before the former can be. It shouldn’t take more than 1 minute to understand what a function does. In the above case, our failing test case is actually a result of a test that is too strict. 999999] np. allclose(a, b, rtol=1e-05, atol=1e-08, equal_nan=False) [source] Returns True if two arrays are element-wise equal within a tolerance. the movement of single atoms at a given temperature is simulated over time. isclose(a, b, rtol=1. binnings. They are considered equal by default. two-column array of {rtol i, atol i} If this option is not required, the actual argument for JAC must be the dummy routine D02NBZ. Fixed for all variables. c f = name of subroutine for right-hand side vector f. {rtol, atol} Relative and absolute tolerance values. Paging is distracting and breaks your concentration. assert_allclose_up_to_global_phase (actual: numpy. June 04, 2014 rtol=1e-07, atol=0) Call np. keep the old `rtol` in other functions and rename `tol`->`atol` parent c26a7bd7. Epsilon comes out in the . We'll test these capabilities out on an Athena dataset. c neq = number of first order ode-s. Source code for openmmtools. modred. Apparently, the default absolute tolerance is 0 and only a relative tolerance is used. The code what you sent is nice. is_rotation (tol=0. Advances in Par Comp for Comp Mech
