EPSErrorView#

Displays the errors associated with the computed solution (as well as the eigenvalues).

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSErrorView(EPS eps,EPSErrorType etype,PetscViewer viewer)

Collective

Input Parameters#

  • eps - the eigensolver context

  • etype - error type

  • viewer - optional visualization context

Options Database Keys#

  • -eps_error_absolute - print absolute errors of each eigenpair

  • -eps_error_relative - print relative errors of each eigenpair

  • -eps_error_backward - print backward errors of each eigenpair

Notes#

By default, this function checks the error of all eigenpairs and prints the eigenvalues if all of them are below the requested tolerance. If the viewer has format=PETSC_VIEWER_ASCII_INFO_DETAIL then a table with eigenvalues and corresponding errors is printed.
