good!

Thanks for you code. It is great! But to address my problem, I need every Gaussion function shares exactly the same width. Is that possible or which part I need to amend?

10 Jun 2011 Gaussian Mixture Model (GMM) - Gaussian Mixture Regression (GMR) Encoding of data in Gaussian Mixture Model and retrieval through Gaussian Mixture Regression Author: Sylvain Calinon Bahareh

I'm trying to implement this for my data but at the first stage, I'm getting the following error:
Warning: Matrix is singular, close to singular or badly scaled.
Results may be inaccurate. RCOND = NaN.
> In gaussPDF at 21
In EM at 94
Can you please help me?

Nice implementation.

Just a tiny little thing: I was wondering why there is no function that computes the output (i.e. the probability) of a learned GMM for a set of data points. I know that it can easily be done by summing the PDFs of all GMM components (using the function gaussPDF(...)) multiplied by their respective prior.
Also, some of the dimensions of the vectors and matrices in the help-text of the function gaussPDF(...) are not correct. It should be:
Mu: D x 1 array
Sigma: D x D array
