SVDSetOptionsPrefix#

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

Synopsis#

#include "slepcsvd.h" 
PetscErrorCode SVDSetOptionsPrefix(SVD svd,const char *prefix)

Logically Collective

Input Parameters#

  • svd - the singular value solver context

  • prefix - the prefix string to prepend to all SVD 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 SVD contexts, one could call

      SVDSetOptionsPrefix(svd1,"svd1_")
      SVDSetOptionsPrefix(svd2,"svd2_")
