Load a 1-D signal. Save the current extension mode.
load noisdopp
x = noisdopp;
origMode = dwtmode('status','nodisp');
Use dwtmode to change the extension mode to zero-padding. Obtain the wavelet packet tree object corresponding to the 3-level wavelet packet decomposition of the signal using the db1 wavelet. Plot the tree.
