# TSRHSJacobianTestTranspose
Compares the multiply transpose routine provided to the MATSHELL with differencing on the TS given RHS function. 
## Synopsis
```
#include "petscts.h"  
PetscErrorCode TSRHSJacobianTestTranspose(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_transpose -*** mat_shell_test_mult_transpose_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
