EPSSetConvergenceTest

Specifies how to compute the error estimate used in the convergence test.

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSSetConvergenceTest(EPS eps,EPSConv conv)
Logically Collective on EPS

Input Parameters

eps - eigensolver context obtained from EPSCreate()
conv - the type of convergence test

Options Database Keys

-eps_conv_abs - Sets the absolute convergence test
-eps_conv_eig - Sets the convergence test relative to the eigenvalue
-eps_conv_norm - Sets the convergence test relative to the matrix norms
-eps_conv_user - Selects the user-defined convergence test

Note

The parameter 'conv' can have one of these values
EPS_CONV_ABS - absolute error ||r||
EPS_CONV_EIG - error relative to the eigenvalue l, ||r||/|l|
EPS_CONV_NORM - error relative to the matrix norms, ||r||/(||A||+|l|*||B||)
EPS_CONV_USER - function set by EPSSetConvergenceTestFunction()
