<h2>
Purpose
</h2>
Computes the posterior probability for each MDN mixture component.

<p><h2>
Synopsis
</h2>
<PRE>
post = mdnpost(mixparams, t)
[post, a] = mdnpost(mixparams, t)
</PRE>


<p><h2>
Description
</h2>
<CODE>post = mdnpost(mixparams, t)</CODE> computes the posterior
probability <CODE>p(j|t)</CODE> of each
data vector in <CODE>t</CODE> under the Gaussian mixture model represented by the
corresponding entries in <CODE>mixparams</CODE>. Each row of <CODE>t</CODE> represents a
single vector.

<p><CODE>[post, a] = mdnpost(mixparams, t)</CODE> also computes the activations
<CODE>a</CODE> (i.e. the probability <CODE>p(t|j)</CODE> of the data conditioned on
each component density) for a Gaussian mixture model.
