drawtree (Wavelet Toolbox)

Draw wavelet packet decomposition tree (GUI)

Syntax

drawtree(T)
drawtree(T,F)
F = drawtree(T)

Description

drawtree(T) draws the wavelet packet tree T, and F = drawtree(T) also returns the figure's handle.

For an existing figure F produced by a previous call to the drawtree function, drawtree(T,F) draws the wavelet packet tree T in the figure whose handle is F. For more information see Chapter 5 of the User's Guide, "Using Wavelet Packets" and Appendix B, "Wavelet Toolbox and Object Programming".

Examples

x   = sin(8*pi*[0:0.005:1]);
t   = wpdec(x,3,'db2');
fig = drawtree(t);


%---------------------------------------
% Use command line function to modify t.
%---------------------------------------
t   = wpjoin(t,2);
drawtree(t,fig);
