WPPursuitTour

Wavelet Packet atomic decomposition

Calling Sequence

[wp, btree] = WPPursuitTour(Format,x,D,qmf [,maxits,title])

Parameters

Inputs:

Format:

string: 'S' for sequential display of four figures 'P' for four-panel display

x :

1-d signal to analyze by Wavelet Packets

D :

fineness of frequency splitting

qmf:

quadrature mirror filter (e.g. Coiflet c3)

natom:

maximum number of atoms to extract by Matching Pursuit

title:

name of signal

Outputs:

atomic:

atoms list, wavelet packet dictionary (see WPPursuit)

resid :

residual

Description

Side Effects plot of Wavelet Packet Synthesis Table plot of Wavelet Packet Residuals Table plot of Compression Numbers plot of phase plane

The format string controls whether all four displays are drawn as subplots in one figure, or whether they are drawn one-after-the-other on the same figure.

The global PREFERIMAGEGRAPHICS controls whether the phase portrait is done using `image' graphics (if =1) or `plot' graphics (if =0).
