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 and Mat
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
