# DMTSSetIJacobian

set TS Jacobian evaluation function

### Synopsis

    #include "petscts.h"
    PetscErrorCode DMTSSetIJacobian(DM dm,TSIJacobian func,void *ctx)

Not Collective

### Input Argument

| dm | - DM to be used with TS
| func | - Jacobian evaluation function, see TSSetIJacobian() for calling sequence
| ctx | - context for residual evaluation

### Note

TSSetJacobian() 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. If DM took a more central role at some later date, this could become the primary method of setting the Jacobian.
