KSPSetGuess#
Set the initial guess object
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPSetGuess(KSP ksp, KSPGuess guess)
Logically Collective
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.
