#include "slepcmfn.h" PetscErrorCode MFNMonitorSet(MFN mfn,PetscErrorCode (*monitor)(MFN mfn,PetscInt its,PetscReal errest,void *mctx),void *mctx,PetscCtxDestroyFn *monitordestroy)Logically Collective
mfn | - matrix function context obtained from MFNCreate() | |
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(MFN mfn,PetscInt its,PetscReal errest,void *mctx)
mfn | - matrix function context obtained from MFNCreate() | |
its | - iteration number | |
errest | - error estimate | |
mctx | - optional monitoring context, as set by MFNMonitorSet() |
-mfn_monitor | - print the error estimate | |
-mfn_monitor draw::draw_lg | - sets line graph monitor for the error estimate | |
-mfn_monitor_cancel | - cancels all monitors that have been hardwired into a code by calls to MFNMonitorSet(), but does not cancel those set via the options database. |
