SNESSetComputeInitialGuess

Sets a routine used to compute an initial guess for the problem

#include "petscsnes.h"  
PetscErrorCode  SNESSetComputeInitialGuess(SNES snes,PetscErrorCode (*func)(SNES,Vec,void*),void *ctx)

Logically Collective on SNES

	snes	- the SNES context
	func	- function evaluation routine
	ctx	- [optional] user-defined context for private data for the function evaluation routine (may be NULL)

   func (SNES snes,Vec x,void *ctx);

f -function vector

ctx -optional user-defined function context
