Mostly a different interface (the underlying lapack function is the
same). What bothers me with the current API for eigen/svd
decompositions is the lack of consistency. The current eigh also does
not enable to look for eigenvalues in a value range (e.g. all eigen
values between 2 and 3), and I intend to add support for non-symmetric
eigenvalues as well.
