SymmetryOrbitEQN.jacobian(**kwargs)[source]

Jacobian matrix evaluated at the current state.

Parameters
kwargs :

Included in signature for derived classes; no usage here.

Returns
np.ndarray :

2-d numpy array equalling the Jacobian matrix of the governing equations evaluated at self.state

Notes

Only need jacobian matrix if direct solvers are used (solvers which solve Ax = b using inverses of A).
