- function waveinfo(wav)
- %WAVEINFO Information on wavelets.
- % WAVEINFO provides information for all the wavelets
- % within the toolbox.
- %
- % WAVEINFO('wname') provides information for the wavelet
- % family whose short name is specified by the string
- % 'wname'.
- %
- % Available family short names are:
- % 'haar' : Haar wavelet.
- % 'db' : Daubechies wavelets.
- % 'sym' : Symlets.
- % 'coif' : Coiflets.
- % 'bior' : Biorthogonal wavelets.
- % 'rbio' : Reverse biorthogonal wavelets.
- % 'meyr' : Meyer wavelet.
- % 'dmey' : Discrete Meyer wavelet.
- % 'gaus' : Gaussian wavelets.
- % 'mexh' : Mexican hat wavelet.
- % 'morl' : Morlet wavelet.
- % 'cgau' : Complex Gaussian wavelets.
- % 'cmor' : Complex Morlet wavelets.
- % 'shan' : Complex Shannon wavelets.
- % 'fbsp' : Complex Frequency B-spline wavelets.
- %
- % or user-defined short names for their own wavelet
- % families (see WAVEMNGR).
- %
- % WAVEINFO('wsys') provides information on wavelet packets.
- %
- % See also WAVEMNGR.
