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().
