mappy_ds.Mode.step#

abstractmethod Mode.step(y0, params=None, *, jacobian=False, hessian=False, trajectory=False, param_keys=None, mixed_hessian=False)#

Evolve y0 through the mode.

Parameters:

y0array_like: Initial state of length dom_dim.
paramsmapping, optional: Parameters of the system.
jacobianbool, optional: Compute the Jacobian matrix of the mode map.
hessianbool, optional: Compute the Hessian tensor of the mode map (implies jacobian).
trajectorybool, optional: Record the trajectory within the mode.
param_keyssequence of str, optional: Compute the derivative of the mode map with respect to these parameters (StepResult.jac_p, one column per key).
mixed_hessianbool, optional: Also compute the mixed second derivative StepResult.hes_p (requires param_keys).

Returns:
