wpviewcf

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 tree T.

T is a wavelet packet tree and CMODE is an integer, which represents the color mode. The color modes are listed in the table below.

Color ModeDescription
1Frequency order – Global coloration – Absolute values
2Frequency order – By level – Absolute values
3Frequency order – Global coloration – Values
4Frequency order – By level coloration – Values
5Natural order – Global coloration – Absolute values
6Natural order – By level – Absolute values
7Natural order – Global coloration – Values
8Natural order – By level coloration – Values

wpviewcf(T,CMODE,NBCOL) uses NBCOL colors.

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 the plot function)
plot(t);

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