04 Jan 2013 Mutual Information Calculates the mutual information between two discrete variables (or a group and a single variable). Author: Will Dwinnell

By "discrete", I mean integer values (intended to act as codes for distinct symbols).

03 Jan 2012 Mutual Information Calculates the mutual information between two discrete variables (or a group and a single variable). Author: Will Dwinnell

This routine is intended for use with discrete variables, not continuous ones.

07 Apr 2011 LDA: Linear Discriminant Analysis Performs linear discriminant analysis. Author: Will Dwinnell

Input and Target are both from the training data. "Input" is a matrix containing the independent variables, while "Target" contains the dependent variable.

Those who cannot find Entropy.m and JointEntropy.m files should search the Matlab File Exchange. These files ara available there, by the same author.

I did not understand the matrix w!
Can you explain it?
