SpectgAs.swf: Spectrogram (in the Time-Frequency plane)
of two slighly different Gabor atoms whose internal frequencies
progressively increase. Note that the result depends highly on the
parameter setting but it shows a lower "resolution" compared with
other decomposition types such as Cohen class distribution.
Time-Frequency plane: abscissa=0,...,1, ordinate=0,...,1. (05').
