#include "slepcmfn.h" 
PetscErrorCode MFNSetOptionsPrefix(MFN mfn,const char *prefix)
Logically Collective on mfn

Input Parameters

mfn  - the matrix function context
prefix  - the prefix string to prepend to all MFN option requests

Notes

A hyphen (-) must NOT be given at the beginning of the prefix name. The first character of all runtime options is AUTOMATICALLY the hyphen.

      MFNSetOptionsPrefix(mfn1,"fun1_")
      MFNSetOptionsPrefix(mfn2,"fun2_")
