TSComputeRHSFunctionLinear#
Evaluate the right-hand side via the user-provided Jacobian, for linear problems Udot = A U only
Synopsis#
#include "petscts.h"
PetscErrorCode TSComputeRHSFunctionLinear(TS ts, PetscReal t, Vec U, Vec F, void *ctx)
Collective
Input Parameters#
ts - time stepping context
t - time at which to evaluate
U - state at which to evaluate
ctx - context
Output Parameter#
F - right-hand side
Note#
This function is intended to be passed to TSSetRHSFunction() to evaluate the right-hand side for linear problems.
The matrix (and optionally the evaluation context) should be passed to TSSetRHSJacobian().
