TSComputeRHSFunctionLinear

Evaluate the right hand side via the user-provided Jacobian, for linear problems 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().
