Selects the particular solver to be used in the SVD object.

Synopsis#

#include "slepcsvd.h" 
PetscErrorCode SVDSetType(SVD svd,SVDType type)

Logically Collective

Input Parameters#

svd - the singular value solver context
type - a known method

Options Database Key#

-svd_type - Sets the method; use -help for a list of available methods

Notes#

See SVDType for available methods. The default is SVDCROSS.

Normally, it is best to use the SVDSetFromOptions() command and then set the SVD 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 SVDSetType() routine is provided for those situations where it is necessary to set the iterative solver independently of the command line or options database.
