DEMO_GABMULAPPR Approximate a slowly time variant system by a Gabor multiplier
  
  This script construct a slowly time variant system and performs the 
  best approximation by a Gabor multiplier with specified parameters
  (a and L see below). Then it shows the action of the slowly time 
  variant system (A) as well as of the best approximation of (A) by a 
  Gabor multiplier (B) on a sinusoids and an exponential sweep.

  Figure 1: Spectrogram of signals

     The figure shows the spectogram of the output of the two systems applied on a 
     sinusoid (left) and an exponential sweep.
