WPTour

Wavelet packet decomposition and Best Basis analysis

Calling Sequence

[wp, btree] = WPTour(Format,x,D,qmf,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

title :

name of signal

Outputs:

wp :

Wavelet packet table (see WPAnalysis)

btree :

basis tree of best time-frequency basis

Description

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).

Side Effects plot of Wavelet packet Table tree plot, best basis phase plot, best basis printout, entropy, best basis
