SVDSetSignature#

Set the signature matrix defining a hyperbolic singular value problem.

Synopsis#

#include "slepcsvd.h" 
PetscErrorCode SVDSetSignature(SVD svd,Vec omega)

Collective

Input Parameters#

  • svd - the singular value solver context

  • omega - a vector containing the diagonal elements of the signature matrix (or NULL)

Notes#

The signature matrix is relevant only for hyperbolic problems (HSVD). Use NULL to reset a previously set signature.
