％ DYNMODES calculates ocean dynamic vertical modes
％ taking a column vector of Brunt-Vaisala values (Nsq) at
％ different pressures (p) and calculating some number of
％ dynamic modes (nmodes).
％ Note: The input pressures need not be uniformly spaced,
％ and the deepest pressure is assumed to be the bottom.
