#include "slepclme.h" PetscErrorCode LMEMonitorSet(LME lme,PetscErrorCode (*monitor)(LME lme,PetscInt its,PetscReal errest,void*mctx),void *mctx,PetscCtxDestroyFn *monitordestroy)Logically Collective
lme | - linear matrix equation solver context obtained from LMECreate() | |
monitor | - pointer to function (if this is NULL, it turns off monitoring) | |
mctx | - [optional] context for private data for the monitor routine (use NULL if no context is desired) | |
monitordestroy | - [optional] routine that frees monitor context (may be NULL), see PetscCtxDestroyFn for the calling sequence |
PetscErrorCode monitor(LME lme,PetscInt its,PetscReal errest,void*mctx)
lme | - linear matrix equation solver context obtained from LMECreate() | |
its | - iteration number | |
errest | - error estimate | |
mctx | - optional monitoring context, as set by LMEMonitorSet() |
-lme_monitor | - print the error estimate | |
-lme_monitor draw::draw_lg | - sets line graph monitor for the error estimate | |
-lme_monitor_cancel | - cancels all monitors that have been hardwired into a code by calls to LMEMonitorSet(), but does not cancel those set via the options database. |
