NEPSetConvergenceTest#

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

Synopsis#

#include "slepcnep.h" 
PetscErrorCode NEPSetConvergenceTest(NEP nep,NEPConv conv)

Logically Collective

Input Parameters#

  • nep - the nonlinear eigensolver context

  • conv - the type of convergence test

Options Database Keys#

  • -nep_conv_abs - Sets the absolute convergence test

  • -nep_conv_rel - Sets the convergence test relative to the eigenvalue

  • -nep_conv_user - Selects the user-defined convergence test

Note#

The parameter ‘conv’ can have one of these values

  • NEP_CONV_ABS - absolute error ||r||

  • NEP_CONV_REL - error relative to the eigenvalue l, ||r||/|l|

  • NEP_CONV_NORM - error relative matrix norms, ||r||/sum_i(|f_i(l)|*||A_i||)

  • NEP_CONV_USER - function set by NEPSetConvergenceTestFunction()
