# 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


## Input Parameter

- ***TS -*** the time stepping routine



## Output Parameter

- ***flg -*** `PETSC_TRUE` if the multiply is likely correct



## Options Database Key

- ***-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 using `TSSetRHSFunction()` and Jacobian NOT `TSSetIFunction()` and Jacobian
