#include "petsctao.h" PetscErrorCode TaoSetTolerances(Tao tao, PetscReal fatol, PetscReal frtol, PetscReal gatol, PetscReal grtol, PetscReal gttol)Logically collective on Tao
| tao | - the Tao context | |
| fatol | - absolute convergence tolerance | |
| frtol | - relative convergence tolerance | |
| gatol | - stop if norm of gradient is less than this | |
| grtol | - stop if relative norm of gradient is less than this | |
| gttol | - stop if norm of gradient is reduced by this factor |
| -tao_fatol <fatol> | - Sets fatol | |
| -tao_frtol <frtol> | - Sets frtol | |
| -tao_gatol <gatol> | - Sets gatol | |
| -tao_grtol <grtol> | - Sets grtol | |
| -tao_gttol <gttol> | - Sets gttol |
