<h2>
Purpose
</h2>
Demonstrate EM for Gaussian mixtures.
<p><h2>
Synopsis
</h2>
<PRE>
demgmm1</PRE>
<p><h2>
Description
</h2>
This script demonstrates the use of the EM algorithm to fit a mixture
of Gaussians to a set of data using maximum likelihood. A colour
coding scheme is used to illustrate the evaluation of the posterior
probabilities in the E-step of the EM algorithm.
