%% MRA Using the Default Wavelet % Construct a multiresolution analysis for the Southern Oscillation Index % data. The sampling period is one day. Plot the level eight details % corresponding to a scale of $2^8$ days. The details at this scale capture % oscillations on a scale of approximately one year. % Copyright 2015 The MathWorks, Inc. load soi wtsoi = modwt(soi); mrasoi = modwtmra(wtsoi); plot(mrasoi(8,:)) title('Level 8 Details')
