Plot wavelet packets colored coefficients

Syntax

wpviewcf (T,CMODE)
wpviewcf (T,CMODE,NBCOL)

Description

wpviewcf (T,CMODE)plots the colored coefficients for the terminal nodes of the treeT.

Tis a wavelet packet tree andCMODEis an integer, which represents the color mode. The color modes are listed in the table below.

Color Mode Description
1 Frequency order – Global coloration – Absolute values
2 Frequency order – By level – Absolute values
3 Frequency order – Global coloration – Values
4 Frequency order – By level coloration – Values
5 自然秩序Abso——全球着色lute values
6 Natural order – By level – Absolute values
7 Natural order – Global coloration – Values
8 Natural order – By level coloration – Values

wpviewcf (T,CMODE,NBCOL)usesNBCOLcolors.

Examples

% Create a wavelet packet tree. x = sin(8*pi*[0:0.005:1]); t = wpdec(x,3,'db1'); % Plot tree t. % Click the node (3,0), (see theplotfunction) plot(t);

% Plot the colored wavelet packet coefficients. wpviewcf(t,1);
