TSComputeIJacobianP#

Runs the user-defined IJacobianP function.

Synopsis#

#include <petscts.h>  
PetscErrorCode TSComputeIJacobianP(TS ts, PetscReal t, Vec U, Vec Udot, PetscReal shift, Mat Amat, PetscBool imex)

Collective

Input Parameters#

ts - the TS context
t - current timestep
U - state vector
Udot - time derivative of state vector
shift - shift to apply, see note below
imex - flag indicates if the method is IMEX so that the RHSJacobianP should be kept separate

Output Parameter#

Amat - Jacobian matrix
