It does for real-symmetric and complex Hermitian matrices, i.e. the $u and
$v from svd() are the same as $vectors from eigen() for Hermitian matrices.
There might be differences in signs, but that does not matter. Of course the
singular values and eigenvalues are identical too.

svd() does not return eigeinvectors!
