MORSEXPAND is the jWavelet module of jLab.

 MORSEXPAND  Generalized Morse wavelets via time-domain Taylor series.
    PSI=MORSEXPAND(T,GAMMA,BETA,FS) computes the lowest-order generalized
    Morse wavelet specified by parameters GAMMA and BETA, and having a peak
    frequency at *radian* frequency FS, using a time-domain Taylor series.
    Normally one would use MORSEWAVE to compute the wavelets in the
    frequency domain, but it is sometimes useful to have an explicit
    time-domain representation.
    There are no contraints on the size of T nor its ordering.  
    All input parameters other than T should be scalars.
    MORSEXPAND can use one of two different algorithms.
    MORSEXPAND(,...,'moment'), the default behavior,  Taylor-expands the
    time-domain wavelet directly.
    MORSEXPAND(,...,'cumulant') expands the logarithm of the time-domain 
    wavelet and then takes the exponential. 
    MORSEXPAND(N,...) specifies the number of terms to include in the
    Taylor expansion.  N defaults to 10 in the 'cumulant' case and 100 in
    the 'moment' case.
    These algorithms implement equations (30) and (31) of Lilly and
    Olhede (2009).

            wavelets.  IEEE Trans. Sig. Proc., 57 (1), 146--160.
    'morsexpand --t' runs a test.
    Usage: psi=morsexpand(t,gamma,beta,fs);
