#include "petscksp.h" #include "petscmat.h" PetscErrorCode KSPSetInitialGuessNonzero(KSP ksp,PetscBool flg)Logically Collective on ksp
| ksp | - iterative context obtained from KSPCreate() | |
| flg | - PETSC_TRUE indicates the guess is non-zero, PETSC_FALSE indicates the guess is zero |
| -ksp_initial_guess_nonzero : use nonzero initial guess; this takes an optional truth value (0/1/no/yes/true/false) |
