opWavelet   Wavelet operator.
 
    opWavelet(M,N,FAMILY) creates a Wavelet operator of given FAMILY for
    signals of size M-by-N. The wavelet transformation is computed using
    the Rice Wavelet Toolbox.  The values supported for FAMILY are
    'Daubechies' and 'Haar'.
 
    opWavelet(M,N,FAMILY,FILTER,LEVELS,REDUNDANT,TYPE) allows for four
    additional parameters: FILTER (default 8) specifies the filter length,
    which must be even. LEVELS (default 5) gives the number of levels in
    the transformation. Both P and Q must be divisible by 2^LEVELS. The
    Boolean field REDUNDANT (default false) indicates whether the wavelet
    is redundant. TYPE (default 'min') indictates what type of solution is
    desired; 'min' for minimum phase, 'max' for maximum phase, and 'mid'
    for mid-phase solutions.
