Sets the function to use for computing the Jacobian.
Synopsis
#include "petscmat.h"
int MatFDColoringSetFunction(MatFDColoring matfd,int (*f)(void),void *fctx)
Collective on MatFDColoring
Input Parameters
| coloring | - the coloring context
|
| f | - the function
|
| fctx | - the optional user-defined function context

Notes
In Fortran you must call MatFDColoringSetFunctionSNES() for a coloring object to
be used with the SNES solvers and MatFDColoringSetFunctionTS() if it is to be used
with the TS solvers.
