+%   Examples:

+%   In the following example the signal *bat* is analyzed through a wavelet 
+%   frame. The result are the frame coefficients associated with the input  
+%   signal *bat* and the analysis frame `’fwt’`.:::
+%
+%      f = bat;
+%      w = 'sym8';
+%      J = 7;
+%      F = frame('fwt', w, J); 
+%      c = frana(F, f);
+%      % A plot of the frame coefficients
+%      plotframe(F, c, 'dynrange', 100);
