# DMTSSetIJacobianContextDestroy
set `TS` Jacobian evaluation context destroy function 
## Synopsis
```
#include "petscts.h" 
PetscErrorCode DMTSSetIJacobianContextDestroy(DM dm, PetscErrorCode (*f)(void *))
```
Not Collective


## Input Parameters

- ***dm -*** `DM` to be used with `TS`
- ***f -*** Jacobian evaluation context destroy function





## Note
`TSSetIJacobianContextDestroy()` is normally used, but it calls this function internally because the user context is actually
associated with the `DM`.  This makes the interface consistent regardless of whether the user interacts with a `DM` or
not.


## Developer Note
If `DM` took a more central role at some later date, this could become the primary method of setting the Jacobian.
