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()
