DEMO_NSDGT  Non-stationary Gabor transform demo

  This script sets up a non-stationary Gabor frame with the specified
  parameters, computes windows and corresponding canonical dual windows
  and a test signal, and plots the windows and the energy of the 
  coefficients.

  Figure 1: Windows + dual windows

     This figure shows the window functions used and the corresponding
     canonical dual windows. 

  Figure 2: Spectrogram (absolute value of coefficients in dB)

     This figure shows a (colour-coded) image of the nsdgt coefficient
     modulus.
