Compares the multiply routine provided to the MATSHELL with differencing on the TS given RHS function.

Synopsis

#include "petscts.h"  
PetscErrorCode  TSRHSJacobianTest(TS ts,PetscBool *flg)
Logically Collective on TS

Input Parameters

TS - the time stepping routine

Output Parameter

flg -PETSC_TRUE if the multiply is likely correct

Options Database

. -ts_rhs_jacobian_test_mult -mat_shell_test_mult_view - run the test at each timestep of the integrator

Notes

This only works for problems defined only the RHS function and Jacobian NOT IFunction and IJacobian
