MFNSetErrorIfNotConverged

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

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

Logically Collective

	mfn	- the matrix function context
	flg	- PETSC_TRUE indicates you want the error generated

-mfn_error_if_not_converged

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

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