LMEMonitorSet
Sets an ADDITIONAL function to be called at every iteration to monitor convergence. 
Synopsis
#include "slepclme.h" 
PetscErrorCode LMEMonitorSet(LME lme,PetscErrorCode (*monitor)(LME lme,PetscInt its,PetscReal errest,void*mctx),void *mctx,PetscErrorCode (*monitordestroy)(void**))
Logically Collective
Input Parameters
|  | 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) | 
Calling sequence of monitor
 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() | 
Options Database Keys
|  | -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. | 
Notes
Several different monitoring routines may be set by calling
LMEMonitorSet() multiple times; all will be called in the
order in which they were set.
