MFNMonitorDefaultDrawLG#

Plots the error estimate of the current approximation at each iteration of the matrix function solver.

Synopsis#

#include "slepcmfn.h" 
PetscErrorCode MFNMonitorDefaultDrawLG(MFN mfn,PetscInt its,PetscReal errest,PetscViewerAndFormat *vf)

Collective

Input Parameters#

  • mfn - the matrix function solver context

  • its - iteration number

  • errest - error estimate

  • vf - viewer and format for monitoring

Options Database Key#

Notes#

This is not called directly by users, rather one calls MFNMonitorSet(), with this function as an argument, to cause the monitor to be used during the MFN solve.

Call MFNMonitorDefaultDrawLGCreate() to create the context used with this monitor.
