Hi, cjain, you have function call mu in path. It is your problem to solve, not mine.

15 Dec 2014 Normalized Mutual Information Fully vectorized implementation normalized mutual information Author: Mo Chen Ori

Hello,
Why is it important to verify the integrity of results, i.e. length(labels)==length(results)?

Isn't it possible to use nmi for clustering with k that is different from number of labels?

I changed the script for my use so that it will accept this. should I upload?

to avoid the error when calling sparse function, just invert x (and y) with 1.
Mx=sparse(idx,1,x,n,k,n);
Please next time refer to the help of sparse function before asking :)

Is the output of the conditionalEntropy function a normalized value? I ask this because, I computed conditional entropy myself with the aid of MutualInformation function and MATLAB's entropy() method. I had got values of conditional Entropy to be greater than 1, which was expected. However, I am getting all conditional entropy values < 1 using InfoTheory toolbox's conditonalEntropy() function.

Has the output been normalized?
Please let me know. Thanks

I got different result using entropy(sig) and wentropy(sig,'shannon'). Can any one explain this?
