    %% Return Nodes of Wavelet Packet Tree
% This example shows how to obtain the depth-position and linear indices
% of a wavelet packet tree.
%%
% Load the noisy Doppler signal and obtain the wavelet packet decomposition
% down to the level 4 using the |'db2'| wavelet.

load noisdopp;
T = wpdec(noisdopp,4,'db2');
%%
% Obtain the depth-position indices.
DepthPosition = allnodes(T,'deppos');
%%
% Obtain the corresponding linear indices.
LinearIndices = allnodes(T);
%%
% Display the correspondance in a table.
