12 Jun 2011 Mutual Information computation A self-contained package for computing mutual information, joint/conditional probability, entropy Author: Hanchuan Peng

Although this is a fast routine, the Mutual Information value for small length vector does not seem to be very reliable when using the same vector as X and Y.
Trying the following small test code ...

clc
clear all
close all

nN = 5000;

fMIacc = zeros(1, nN);

figure
hold on
for i = 1:nN
    fVec = rand(1,i);
    fMI = mutualinfo(fVec,fVec);
    fMIacc(1, i) = fMI;
end
plot(fMIacc)
axis([-100 nN+1 0 1.5])
