readtree

(Removed) Read wavelet packet decomposition tree from figure

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

Syntax

T = readtree(F)

T = readtree(F) reads the wavelet packet tree T from the figure whose handle is F.

Create a wavelet packet tree.

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

Display the tree.

fig = drawtree(t);

Use the GUI to merge tree nodes.

Read the tree from the GUI. Use plot to plot the tree. Click the node (3,0).

t = readtree(fig);
plot(t)

Handle to the figure, specified as a figure handle.

Introduced before R2006a

The Wavelet Analyzer app has been removed. readtree 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. readtree 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.
