    Open Live Script

    Create a wavelet packet tree.

    x = randn(1,1000);
t = wpdec(x,3,"db2");

    Merge the nodes with indices 3 and 5. Plot the modified tree.

    t = nodejoin(t,3);
t = nodejoin(t,5);
fig = plot(t);

    Figure contains 2 axes objects and other objects of type uimenu. Axes object 1 with title Tree Decomposition contains 21 objects of type line, text. Axes object 2 with title data for node: 0 or (0,0). contains an object of type line.

    Programmatically, in Node Label, change the selected item from Depth_Position to Index.

    plot(t,"setNodeLabel",fig,"Index")

    Figure contains 2 axes objects and other objects of type uimenu. Axes object 1 with title Tree Decomposition contains 21 objects of type line, text. Axes object 2 with title data for node: 0 or (0,0). contains an object of type line.

    Display the contents of the modified tree.
