25 Description
26 </h2>
27 <CODE>post = mdnpost(mixparams, t)</CODE> computes the posterior
28 probability <CODE>p(j|t)</CODE> of each
29 data vector in <CODE>t</CODE> under the Gaussian mixture model represented by the
30 corresponding entries in <CODE>mixparams</CODE>. Each row of <CODE>t</CODE> represents a
31 single vector.
32
33 <p><CODE>[post, a] = mdnpost(mixparams, t)</CODE> also computes the activations
34 <CODE>a</CODE> (i.e. the probability <CODE>p(t|j)</CODE> of the data conditioned on
35 each component density) for a Gaussian mixture model.
