TSSetRHSJacobianP

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

PetscErrorCode TSSetRHSJacobianP(TS ts,Mat Amat,PetscErrorCode (*func)(TS,PetscReal,Vec,Mat,void*),void *ctx)

Logically Collective on TS

	ts	- The TS context obtained from TSCreate()
	func	- The function

func (TS ts,PetscReal t,Vec y,Mat A,void *ctx);

	t	- current timestep
	y	- input vector (current ODE solution)
	A	- output matrix
	ctx	- [optional] user-defined function context

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
