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 on TS
Input Arguments
| ts | - time stepping context
|
| t | - time at which to evaluate
|
| U | - state at which to evaluate
|
| ctx | - context
|
Output Arguments
F -right hand side
Notes
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().
