MFNSetOptionsPrefix#

Sets the prefix used for searching for all MFN options in the database.

Synopsis#

#include "slepcmfn.h" 
PetscErrorCode MFNSetOptionsPrefix(MFN mfn,const char prefix[])

Logically Collective

Input Parameters#

  • mfn - the matrix function solver 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.

For example, to distinguish between the runtime options for two different MFN contexts, one could call

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