TSRHSSplitSetRHSFunction

Set the split right-hand-side functions.

#include "petscts.h"  
PetscErrorCode TSRHSSplitSetRHSFunction(TS ts,const char splitname[],Vec r,TSRHSFunction rhsfunc,void *ctx)

Logically Collective on TS

	ts	- the TS context obtained from TSCreate()
	splitname	- name of this split
	r	- vector to hold the residual (or NULL to have it created internally)
	rhsfunc	- the RHS function evaluation routine
	ctx	- user-defined context for private data for the split function evaluation routine (may be NULL)

 rhsfunc(TS ts,PetscReal t,Vec u,Vec f,ctx);

	t	- time at step/stage being solved
	u	- state vector
	f	- function vector
	ctx	- [optional] user-defined context for matrix evaluation routine (may be NULL)
