Wavelet packet decomposition and Best Basis analysis
[wp, btree] = WPTour(Format,x,D,qmf,title)
string: 'S' for sequential display of four figures 'P' for four-panel display
1-d signal to analyze by Wavelet Packets
fineness of frequency splitting
name of signal
Wavelet packet table (see WPAnalysis)
basis tree of best time-frequency basis
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).
