<h2>
Purpose
</h2>
Converts an MDN mixture data structure to array of GMMs.
<p><h2>
Synopsis
</h2>
<PRE>
gmmmixes = mdn2gmm(mdnmixes)
</PRE>
<p><h2>
Description
</h2>
<CODE>gmmmixes = mdn2gmm(mdnmixes)</CODE> takes an MDN mixture data structure
<CODE>mdnmixes</CODE>
containing three matrices (for priors, centres and variances) where each
row represents the corresponding parameter values for a different mixture model
and creates an array of GMMs. These can then be used with the standard
Netlab Gaussian mixture model functions.
<p><h2>
Example
</h2>
<PRE>
mdnmixes = mdnfwd(net, x);
mixes = mdn2gmm(mdnmixes);
p = gmmprob(mixes(1), y);
</PRE>
This creates an array GMM mixture models (one for each data point in
<CODE>x</CODE>). The vector <CODE>p</CODE> is then filled with the conditional
probabilities of the values <CODE>y</CODE> given <CODE>x(1,:)</CODE>.
