MORSEHIGH is the jWavelet module of jLab.

 MORSEHIGH  High-frequency cutoff of the generalized Morse wavelets.
    MORSEHIGH is a low-level function called by MORSESPACE in order to 
    set the high-frequency cutoff of the wavelet transform.
    FHIGH=MORSEHIGH(GAMMA,BETA,ETA) returns the high-frequency cutoff
    FHIGH of the generalized Morse wavelet specified by GAMMA and BETA, 
    with cutoff level ETA.
    Specifically, FHIGH will give the highest possible radian frequency 
    for which the generalized Morse wavelet MORSEWAVE(N,GAMMA,BETA,FHIGH)
    will have a greater than ETA times its maximum value at the Nyquist.
    Here N is any choice of wavelet length.
    If F=MORSEFREQ(GAMMA,BETA) is the wavelet peak frequency, then 
       PSI(PI*F/FHIGH) <= ETA * PSI(F) 
    is the cutoff condition. See Appendix C of Lilly (2017) for details. 
    The input parameters may either all be scalars, or GAMMA and BETA
    may be arrays of the same size with scalar ALPHA.
    Usage: falpha=morsehigh(ga,be,alpha);
