Synopsis#
#include "slepcmfn.h"
PetscErrorCode MFNSetType(MFN mfn,MFNType type)
Logically Collective
Input Parameters#
mfn - the matrix function solver context
type - a known method
Options Database Key#
-mfn_type
- Sets the method; use-helpfor a list of available methods
Notes#
See MFNType for available methods. The default is MFNKRYLOV.
Normally, it is best to use the MFNSetFromOptions() command and
then set the MFN type from the options database rather than by using
this routine. Using the options database provides the user with
maximum flexibility in evaluating the different available methods.
The MFNSetType() routine is provided for those situations where it
is necessary to set the iterative solver independently of the command
line or options database.
