PEPSetConvergenceTest

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

Synopsis

#include "slepcpep.h" 
PetscErrorCode PEPSetConvergenceTest(PEP pep,PEPConv conv)
Logically Collective on PEP

Input Parameters

pep - eigensolver context obtained from PEPCreate()
conv - the type of convergence test

Options Database Keys

-pep_conv_abs - Sets the absolute convergence test
-pep_conv_eig - Sets the convergence test relative to the eigenvalue
-pep_conv_linear - Sets the convergence test related to the linearized eigenproblem
-pep_conv_user - Selects the user-defined convergence test

Note

The parameter 'conv' can have one of these values
PEP_CONV_ABS - absolute error ||r||
PEP_CONV_EIG - error relative to the eigenvalue l, ||r||/|l|
PEP_CONV_LINEAR - error related to the linearized eigenproblem
PEP_CONV_NORM - error relative matrix norms, ||r||/sum_i(l^i*||A_i||)
PEP_CONV_USER - function set by PEPSetConvergenceTestFunction()
