Function: gabrieszbounds

GABRIESZBOUNDS  Calculate Riesz sequence/basis bounds of Gabor frame
  Usage:  fcond=gabrieszbounds(g,a,M);
          [A,B]=gabrieszbounds(g,a,M);
          [A,B]=gabrieszbounds(g,a,M,L);

  Input parameters:
          g     : The window function.
          a     : Length of time shift.
          M     : Number of channels.
          L     : Length of transform to consider.
  Output parameters:
          fcond : Frame condition number (B/A)
          A,B   : Frame bounds.
         
  GABRIESZBOUNDS(g,a,M) calculates the ratio B/A of the Riesz bounds
  of the Gabor system with window g, and parameters a, M.

  [A,B]=GABRIESZBOUNDS(g,a,M) calculates the Riesz bounds A and B*
  instead of just the ratio.

  The window g may be a vector of numerical values, a text string or a
  cell array. See the help of GABWIN for more details.
 
  If the optional parameter L is specified, the window is cut or
  zero-extended to length L.
