EPSMonitorFirstDrawLG#

Plots the error estimate of the first unconverged approximation at each iteration of the eigensolver.

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSMonitorFirstDrawLG(EPS eps,PetscInt its,PetscInt nconv,PetscScalar eigr[],PetscScalar eigi[],PetscReal errest[],PetscInt nest,PetscViewerAndFormat *vf)

Collective

Input Parameters#

  • eps - the linear eigensolver context

  • its - iteration number

  • nconv - number of converged eigenpairs so far

  • eigr - real part of the eigenvalues

  • eigi - imaginary part of the eigenvalues

  • errest - error estimates

  • nest - number of error estimates to display

  • vf - viewer and format for monitoring

Notes#

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

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