SVDSetProblemType

Specifies the type of the singular value problem.

Synopsis

#include "slepcsvd.h" 
PetscErrorCode SVDSetProblemType(SVD svd,SVDProblemType type)

Logically Collective

Input Parameters

	svd	- the singular value solver context
	type	- a known type of singular value problem

Options Database Keys

	-svd_standard	- standard singular value decomposition (SVD)
	-svd_generalized	- generalized singular value problem (GSVD)
	-svd_hyperbolic	- hyperbolic singular value problem (HSVD)

Notes

The GSVD requires that two matrices have been passed via SVDSetOperators(). The HSVD requires that a signature matrix has been passed via SVDSetSignature().
