MFNSetErrorIfNotConverged#

Causes MFNSolve() to generate an error if the solver has not converged.

Synopsis#

#include "slepcmfn.h" 
PetscErrorCode MFNSetErrorIfNotConverged(MFN mfn,PetscBool flg)

Logically Collective

Input Parameters#

  • mfn - the matrix function context

  • flg - PETSC_TRUE indicates you want the error generated

Options Database Keys#

  • -mfn_error_if_not_converged - this takes an optional truth value (0/1/no/yes/true/false)

Note#

Normally SLEPc continues if the solver fails to converge, you can call MFNGetConvergedReason() after a MFNSolve() to determine if it has converged.
