# TSSetRHSJacobianP

Sets the function that computes the Jacobian of \(G\) w.r.t. the parameters \(p\) where \(U_t = G(U,p,t)\), as well as the location to store the matrix.

## Synopsis

    #include <petscts.h>
    PetscErrorCode TSSetRHSJacobianP(TS ts, Mat Amat, TSRHSJacobianPFn *func, PetscCtx ctx)

Logically Collective

## Input Parameters

- ts - `TS` context obtained from `TSCreate()`

- Amat - JacobianP matrix

- func - function

- ctx - [optional] function context

## Note

`Amat` has the same number of rows and the same row parallel layout as `u`, `Amat` has the same number of columns and parallel layout as `p`
