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

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_rel  - 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_REL  - 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()
