wpviewcf (Wavelet Toolbox)

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 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
Natural order - Global coloration - Absolute values

            6
Natural order - By level - Absolute values

            7
Natural order - Global coloration - Values

            8
Natural order - By level coloration - Values

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	Natural order - Global coloration - Absolute 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) 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);
