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.
