%% Depth and Position in Wavelet Packet Tree % Create a binary wavelet packet tree with three levels. % Copyright 2015 The MathWorks, Inc. Ord = 2; Lev = 3; T = ntree(Ord,Lev); %% % Plot the binary wavelet packet tree. plot(T) %% % Obtain the indices of the nodes in linear order. idx = allnodes(T); %% % Conver the indices to depth-position format. [depth,pos] = ind2depo(Ord,idx); table(depth,pos)
