drawtree

(Removed) Draw wavelet packet decomposition tree (GUI)

Wavelet Analyzer has been removed. drawtree is part of Wavelet Analyzer. For recommended alternatives, see Version History.

Syntax

drawtree(T)

fig = drawtree(T)

drawtree(T,F)

drawtree(T) draws the wavelet packet tree T.

fig = drawtree(T) returns the figure handle.

drawtree(T,F) draws the wavelet packet tree T in the existing figure F.

Create a wavelet packet tree and draw the result.

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

Modify the tree and draw the result in the existing figure.

t   = wpjoin(t,2);
drawtree(t,fig);

Tree, specified as a dtree, ntree, or wptree object.

Handle to the figure, specified as a figure handle. F must be a handle to a figure produced by a previous call to drawtree.

Introduced before R2006a

The Wavelet Analyzer app has been removed. drawtree is part of Wavelet Analyzer.

To perform signal multiresolution analysis using wavelet and data-adaptive techniques, use the Signal Multiresolution Analyzer app.
To analyze images using the discrete wavelet or continuous wavelet transforms, use the Wavelet Image Analyzer app.
To analyze and compress signals using discrete wavelet or wavelet packet transforms, use the Wavelet Signal Analyzer app.
To analyze and denoise signals using the discrete wavelet transform, use the Wavelet Signal Denoiser app.
To perform time-frequency analysis of signals using the continuous wavelet transform, use the Wavelet Time-Frequency Analyzer app.

The Wavelet Analyzer app is no longer recommended and will be removed in a future release. drawtree is part of Wavelet Analyzer.

For time-frequency analysis, use the Wavelet Time-Frequency Analyzer app.
For wavelet signal denoising, use the Wavelet Signal Denoiser app.
For signal multiresolution analysis, use the Signal Multiresolution Analyzer app.
