TīmeklisThere are three ways to define the Jacobian: If array_like or sparse_matrix, the Jacobian is assumed to be constant. If callable, the Jacobian is assumed to depend on both t and y; it will be called as jac (t, y) as necessary. For the ‘Radau’ and ‘BDF’ methods, the return value might be a sparse matrix. If None (default), the Jacobian ... Tīmeklis2024. gada 28. apr. · To perform ODE, SciPy provides the following routines. Solving initial value problems for ODE systems.

TīmeklisPython ODE Solvers ... As suggested by the documentation, you should use the ‘RK45’ or ‘RK23’ method for non-stiff problems and ‘Radau’ or ‘BDF’ for stiff problems. If not sure, first try to run ‘RK45’. If needs unusually many iterations, diverges, or fails, your problem is likely to be stiff and you should use ‘Radau ...
