number of frequencies for which gabor transform
is to be computed.
freqstep
Sampling rate for the frequency axis.
scale
Size parameter for the window.
plot
logical variable set to TRUE to display the modulus of the
continuous gabor transform on the graphic device.
Value
continuous (complex) gabor transform (2D array).
Warning
freqstep must be less than 1/nvoice to avoid aliasing. freqstep=1/nvoice
corresponds to the Nyquist limit.
Details
The output contains the (complex) values of the gabor transform of the
input signal. The format of the output is
a 2D array (signal\_size x nb\_scales).
