#include "petscts.h" PetscErrorCode TSGetRHSJacobian(TS ts,Mat *Amat,Mat *Pmat,TSRHSJacobian *func,void **ctx)Not Collective, but parallel objects are returned if TS is parallel
|Amat||- The (approximate) Jacobian J of G, where U_t = G(U,t) (or NULL)|
|Pmat||- The matrix from which the preconditioner is constructed, usually the same as Amat (or NULL)|
|func||- Function to compute the Jacobian of the RHS (or NULL)|
|ctx||- User-defined context for Jacobian evaluation routine (or NULL)|
Notes: You can pass in NULL for any return argument you do not need.
