Detailed Description

template<typename real_type>
struct molpro::linalg::itsolv::detail::eigenvalue_order< real_type >

Orders eigenvalues by non-descending real part, then by imaginary part.

The magnitude of the imaginary part is compared before its sign so that distinct complex pairs sharing a real part stay together, and the two members of a pair come out in a fixed order.
