plotmatrixandr, plotmatrixpara

Constructs a plotmatrix where each set of axes contains either Andrews' curves or parallel coordinate plots. This constructs a plotmatrix with p plots for an n by p matrix X.

Input Arguments:

• X is the n by p data matrix.
• CLASSLAB is an n-element vector containing the numeric class labels.
• MAP is an optional argument that is either a colormap matrix (3 columns - RGB values) or a cell array of strings containing the usual MATLAB color code strings. (See help on PLOT for more information.) Default colors are used if this is not present.
• TITLESTR is an optional input argument for a plot title. Use the empty matrix [] if you do not use the 'map' option, but you want a title.

Output Arguments:

• None

Synopsis

PLOTMATRIXANDR(X,CLASSLAB,MAP,TITLESTR)

PLOTMATRIXPARA(X,CLASSLAB,MAP,TITLESTR)

Examples:

% plotmatrixpara(X,classlabs) % Default colors, no title
% plotmatrixpara(X,classlabs,[],'My Plot') % Default colors, with title
% plotmatrixpara(X,classlabs,{'k','m'}) % No title, colors black and magenta are used

% plotmatrixandr(X,classlabs) % Default colors, no title
% plotmatrixandr(X,classlabs,[],'My Plot') % Default colors, with title
% plotmatrixandr(X,classlabs,{'k','m'}) % No title, colors black and magenta are used
