% adfig06 -- Adapt Figure 06: MultiResolution Analysis of the Four Functions
% 
% Mallat's MRA groups together all the terms in the wavelet 
% decomposition which occupy the same scale (with perhaps
% different locations).
%
% Here we display the MRA of the four functions from Figure 1,
% using the Daubechies Nearly Symmetric S8 Wavelet.
