PetscErrorCode TSComputeRHSJacobian(TS ts, PetscReal t, Vec U, Mat A, Mat B)
Collective
Input Parameters#
- ts - the - TScontext
- t - current timestep 
- U - input vector 
Output Parameters#
- A - Jacobian matrix 
- B - optional preconditioning matrix 
Note#
Most users should not need to explicitly call this routine, as it is used internally within the nonlinear solvers.
