Sets the tolerance and maximum iteration count used by the MFN convergence tests.

Synopsis

#include "slepcmfn.h" 
PetscErrorCode MFNSetTolerances(MFN mfn,PetscReal tol,PetscInt maxits)
Logically Collective on MFN

Input Parameters

mfn - the matrix function context
tol - the convergence tolerance
maxits - maximum number of iterations to use

Options Database Keys

-mfn_tol <tol> - Sets the convergence tolerance
-mfn_max_it <maxits> - Sets the maximum number of iterations allowed

Notes

Use PETSC_DEFAULT for either argument to assign a reasonably good value.
