information
Syntax
Description
Examples
Examine Wavelet Packet Tree Contents
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);
Programmatically, in Node Label, change the selected item from Depth_Position
to Index
.
plot(t,"setNodeLabel",fig,"Index")
Display the contents of the modified tree.
