# 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 on MFN

### 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.
