% toon0433 -- Best-m Compression Numbers of Four Objects
%  
%  Plot the compression numbers for the S8 wavelet transforms
%  of each of the four signals.  These curves illustrate the
%  gain in accuracy obtained by using an additional coefficient
%  in the reconstruction.  These curves are based on taking the
%  best-m coefficients.
