TSSetRHSJacobian

Sets the function to compute the Jacobian of G, where U_t = G(U,t), as well as the location to store the matrix.

PetscErrorCode  TSSetRHSJacobian(TS ts,Mat Amat,Mat Pmat,TSRHSJacobian f,void *ctx)

Logically Collective on TS

	ts	- the TS context obtained from TSCreate()
	Amat	- (approximate) Jacobian matrix
	Pmat	- matrix from which preconditioner is to be constructed (usually the same as Amat)
	f	- the Jacobian evaluation routine
	ctx	- [optional] user-defined context for private data for the Jacobian evaluation routine (may be NULL)

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

	t	- current timestep
	u	- input vector
	Amat	- (approximate) Jacobian matrix
	Pmat	- matrix from which preconditioner is to be constructed (usually the same as Amat)
	ctx	- [optional] user-defined context for matrix evaluation routine
