#include "petscksp.h" PetscErrorCode KSPSetGuess(KSP ksp,KSPGuess guess)Logically Collective on KSP
| 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.
