Abstract
The diagonalization of general mass matrices is a more delicate proble m when eigenvalue degeneracies exist. In this case, often overlooked i n the literature, some difficulties arise related to the freedom in th e choice of basis in degenerate subspaces. Here two simple algorithms are developed to deal with quark and neutrino mass matrices with arbit rary degeneracies.
