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
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_rel - Sets the convergence test relative to the eigenvalue
-pep_conv_norm - Sets the convergence test relative to the matrix norms
-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_REL - error relative to the eigenvalue l, ||r||/|l|
PEP_CONV_NORM - error relative matrix norms, ||r||/sum_i(l^i*||A_i||)
PEP_CONV_USER - function set by PEPSetConvergenceTestFunction()
