NEPMonitorRegister#

Registers a NEP monitor routine that may be accessed with NEPMonitorSetFromOptions().

Synopsis#

#include "slepcnep.h" 
PetscErrorCode NEPMonitorRegister(const char name[],PetscViewerType vtype,PetscViewerFormat format,NEPMonitorRegisterFn *monitor,NEPMonitorRegisterCreateFn *create,NEPMonitorRegisterDestroyFn *destroy)

Not Collective

Input Parameters#

  • name - name of a new monitor routine

  • vtype - a PetscViewerType for the output

  • format - a PetscViewerFormat for the output

  • monitor - monitor routine, see NEPMonitorRegisterFn

  • create - creation routine, or NULL

  • destroy - destruction routine, or NULL

Notes#

NEPMonitorRegister() may be called multiple times to add several user-defined monitors.

The calling sequence for the given function matches the calling sequence of NEPMonitorFn functions passed to NEPMonitorSet() with the additional requirement that its final argument be a PetscViewerAndFormat.

Example Usage#

   NEPMonitorRegister("my_monitor",PETSCVIEWERASCII,PETSC_VIEWER_ASCII_INFO_DETAIL,MyMonitor,NULL,NULL);

Then, your monitor can be chosen with the procedural interface via

NEPMonitorSetFromOptions(nep,"-nep_monitor_my_monitor","my_monitor",NULL)

or at runtime via the option

-nep_monitor_my_monitor
