TSGetRHSJacobian

Returns the Jacobian J at the present timestep.

#include "petscts.h"  
PetscErrorCode  TSGetRHSJacobian(TS ts,Mat *J,Mat *M,TSRHSJacobian *func,void **ctx)

Not Collective, but parallel objects are returned if TS is parallel

ts -The TS context obtained from TSCreate()

	J	- The Jacobian J of F, where U_t = F(U,t)
	M	- The preconditioner matrix, usually the same as J
	func	- Function to compute the Jacobian of the RHS
	ctx	- User-defined context for Jacobian evaluation routine

Notes: You can pass in PETSC_NULL for any return argument you do not need.
