PetscErrorCode SVDSetOptionsPrefix(SVD svd,const char *prefix)
Logically Collective on svd

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.

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