    %% Inverse MODWPT Using Scaling and Wavelet Filters
% Obtain the MODWPT of Southern Oscillation Index data using specified
% scaling and wavelets filters with the Daubechies extremal phase wavelet 
% with two vanishing moments (|'db2'|). 
load soi;
[lo,hi] = wfilters('db2');
wpt = modwpt(soi,lo,hi);
xrec = imodwpt(wpt,lo,hi);

% Plot the original SOI waveform and the reconstructed waveform.
