# DMTSSetI2Jacobian

set `TS` implicit Jacobian evaluation function for 2nd order systems from a `DMTS`

## Synopsis

    #include "petscts.h"
    PetscErrorCode DMTSSetI2Jacobian(DM dm, TSI2JacobianFn *jac, void *ctx)

Not Collective

## Input Parameters

- dm - `DM` to be used with `TS`

- jac - Jacobian evaluation routine

- ctx - context for Jacobian evaluation

## Note

`TSSetI2Jacobian()` is normally used, but it calls this function internally because the user context is actually associated with the `DM`.
