SVDGetSignature#

Get the signature matrix defining a hyperbolic singular value problem.

Synopsis#

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

Not Collective

Input Parameter#

  • svd - the singular value solver context

Output Parameter#

  • omega - a vector containing the diagonal elements of the signature matrix

Notes#

The signature matrix is relevant only for hyperbolic problems (HSVD). If no signature has been set, this function will return a vector of all ones.

The user should pass a previously created Vec with the appropriate dimension.
