number of scales in each octave (i.e. between two consecutive powers of 2).
w0
central frequency of the wavelet.
twoD
logical variable set to T to organize the output as a 2D array
(signal size $\times$ nb scales), otherwise, the output is a 3D
array (signal size $\times$ noctave $\times$ nvoice).
plot
logical variable set to T to T to display the modulus of the squeezed
wavelet transform on the graphic device.
