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.
