DEMO_GABMIXDUAL  How to use GABMIXDUAL

  This script illustrates how one can produce dual windows
  using GABMIXDUAL

  The demo constructs a dual window that is more concentrated in
  the time domain by mixing the original Gabor window by one that is
  extremely well concentrated. The result is somewhat in the middle
  of these two.

  The lower framebound of the mixing Gabor system is horrible,
  but this does not carry over to the gabmixdual.

  Figure 1: Gabmixdual of two Gaussians.

     The first row of the figure shows the canonical dual window
     of the input window, which is a Gaussian function perfectly
     localized in the time and frequency domains.

     The second row shows the canonical dual window of the window we
     will be mixing with: This is a Gaussian that is 10 times more
     concentrated in the time domain than in the frequency domain.
     The resulting canonical dual window has rapid decay in the time domain.

     The last row shows the gabmixdual of these two. This is a non-canonical
     dual window of the first Gaussian, with decay resembling that of the
     second.
