Méthode scipy.integrate.ode.get_return_code

Signature de la méthode get_return_code

def get_return_code(self) 

Description

get_return_code.__doc__

Extracts the return code for the integration to enable better control
        if the integration fails.

        In general, a return code > 0 implies success, while a return code < 0
        implies failure.

        Notes
        -----
        This section describes possible return codes and their meaning, for available
        integrators that can be selected by `set_integrator` method.

        2            Integration successful.
        -1           Excess work done on this call. (Perhaps wrong MF.)
        -2           Excess accuracy requested. (Tolerances too small.)
        -3           Illegal input detected. (See printed message.)
        -4           Repeated error test failures. (Check all input.)
        -5           Repeated convergence failures. (Perhaps bad Jacobian
                     supplied or wrong choice of MF or tolerances.)
        -6           Error weight became zero during problem. (Solution
                     component i vanished, and ATOL or ATOL(i) = 0.)
