DMKSPSetComputeInitialGuess

set KSP initial guess evaluation function

#include "petscksp.h" 
PetscErrorCode DMKSPSetComputeInitialGuess(DM dm,PetscErrorCode (*func)(KSP,Vec,void*),void *ctx)

Not Collective

	dm	- DM to be used with KSP
	func	- initial guess evaluation function, see KSPSetComputeInitialGuess() for calling sequence
	ctx	- context for right hand side evaluation

KSPSetComputeInitialGuess() is normally used, but it calls this function internally because the user context is actually associated with the DM.
