MORSEPROPS is the jWavelet module of jLab.

 MORSEPROPS  Properties of the demodulated generalized Morse wavelets. 
 
    [P,SKEW,KURT]=MORSEPROPS(GAMMA,BETA) returns properties of the 
    demodulated generalized Morse wavelet specified by GAMMA and BETA.
   
    P is the dimensionless time-domain window width.
 
    SKEW is the imaginary part of normalized third moment of the 
    time-domain demodulate, or 'demodulate skewness'.
 
    KURT is the normalized fourth moment of the time-domain demodulate, 
    or 'demodulate kurtosis'.
 
    See Lilly and Olhede (2008b) for details.
 
    See also MORSEFREQ, MORSEBOX, MORSEWAVE.
 
    'morseprops --t' runs a test.
 
    Usage: [p,skew,kurt]=morseprops(ga,be);
