Synopsis
#include "petscksp.h"
PetscErrorCode KSPSetGuess(KSP ksp,KSPGuess guess)
Logically Collective on KSP
Input Parameters
| ksp | - the Krylov context
|
| guess | - the object created with KSPGuessCreate()

Notes
this allows a single KSP to be used with several different initial guess generators (likely for different linear
solvers, see KSPSetPC()).
This increases the reference count of the guess object, you must destroy the object with KSPGuessDestroy()
before the end of the program.
