TSSetRHSFunction

Sets the routine for evaluating the function, F(t,u), where U_t = F(t,u).

#include "petscts.h"  
int TSSetRHSFunction(TS ts,int (*f)(TS,PetscReal,Vec,Vec,void*),void *ctx)

Collective on TS

	ts	- the TS context obtained from TSCreate()
	f	- routine for evaluating the right-hand-side function
	ctx	- [optional] user-defined context for private data for the function evaluation routine (may be PETSC_NULL)

    func (TS ts,PetscReal t,Vec u,Vec F,void *ctx);

	t	- current timestep
	u	- input vector
	F	- function vector
	ctx	- [optional] user-defined function context

The user MUST call either this routine or TSSetRHSMatrix().
