MORSEBOX is the jWavelet module of jLab.

 MORSEBOX  Heisenberg time-frequency box for generalized Morse wavelets.
    A=MORSEBOX(GAMMA,BETA) returns the time-bandwidth product of the
    a generalized Morse wavelet, that is, the area of its Heisenberg box.
    [A,SIGT,SIGO,SKEW]=MORSEBOX(GAMMA,BETA) also returns the box width in 
    time SIGT and in frequency SIGO, with A=SIGT*SIGO, as well as the 
    frequency-domain skewness SKEW.
    Both SIGT and SIGO are non-dimensionalized with respect to the (radian)
    peak frequency MORSEFREQ, as in Lilly and Olhede (2009) given below.
    Not for all values of BETA and GAMMA are these standard derivations
    defined as real-valued quantities.  For locations where these would 
    be imaginary, their values are set to NAN.
    For details see
        Lilly and Olhede (2009).  Higher-order properties of analytic 
            wavelets.  IEEE Trans. Sig. Proc., 57 (1), 146--160.
    In this calculation, care is taken to avoid potential problems caused
    by large arguments to the gamma function, by utilizing GAMMALN.  This
    lets the Heisenberg area be computed for small values of GAMMA/BETA.  
    'morsebox --t' runs a test.
    'morsebox --f' generates a sample figure.
    Usage: a=morsebox(ga,be);
