20 May 2010 Information Theory Toolbox v1.0 Implementation of major algorithms related to information theory for categorical data including a si Author: Joaquín Goñi Aviel, Yuval

All functions here takes random variables as input, not probability distribution, as commonly defined.
This is very confusing.

In addition, these function will probably work on categorical data only.

In the "function kl = kldivergence (x,y)", there is a serious error !
Look at the 62 and 63 line:
ipOcurrences = numel(find(x==valuesX(i))); %computes i-ocurrences at x
iqOcurrences = numel(find(y==valuesY(i))); %computes i-ocurrences at y
Note that valuesX and valuesY are distinct values for vector x and vector y, respectively. But valuesX(i) can be different from valuesY(i). Therefore pi and qi are not probability of the same index !!!!!!

Nice product!!!!!!!!!!!!!!!!!

I want to compute Conditional Mutual Information , can you help me ,it seems that the toolbox does not contain this algorithm.

Hi, why not use vector form ? You can further speed them up using vector form. Keep polishing.
