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 on eps

Input Parameters

	eps	- the eigensolver context
	etype	- error type
	viewer	- optional visualization context

Options Database Key

	-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.
