TSComputeRHSJacobian#

Computes the Jacobian matrix that has been set with TSSetRHSJacobian().

Synopsis#

#include "petscts.h"  
PetscErrorCode TSComputeRHSJacobian(TS ts, PetscReal t, Vec U, Mat A, Mat B)

Collective

Input Parameters#

  • ts - the TS context

  • 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.
