| wolffd@0 | 27 <CODE>post = mdnpost(mixparams, t)</CODE> computes the posterior |
| wolffd@0 | 28 probability <CODE>p(j|t)</CODE> of each |
| wolffd@0 | 29 data vector in <CODE>t</CODE> under the Gaussian mixture model represented by the |
| wolffd@0 | 30 corresponding entries in <CODE>mixparams</CODE>. Each row of <CODE>t</CODE> represents a |
| wolffd@0 | 31 single vector. |
| wolffd@0 | 32 |
| wolffd@0 | 33 <p><CODE>[post, a] = mdnpost(mixparams, t)</CODE> also computes the activations |
| wolffd@0 | 34 <CODE>a</CODE> (i.e. the probability <CODE>p(t|j)</CODE> of the data conditioned on |
| wolffd@0 | 35 each component density) for a Gaussian mixture model. |
