| wolffd@0 | 24 Description |
| wolffd@0 | 25 </h2> |
| wolffd@0 | 26 <CODE>gmmmixes = mdn2gmm(mdnmixes)</CODE> takes an MDN mixture data structure |
| wolffd@0 | 27 <CODE>mdnmixes</CODE> |
| wolffd@0 | 28 containing three matrices (for priors, centres and variances) where each |
| wolffd@0 | 29 row represents the corresponding parameter values for a different mixture model |
| wolffd@0 | 30 and creates an array of GMMs. These can then be used with the standard |
| wolffd@0 | 31 Netlab Gaussian mixture model functions. |
| wolffd@0 | 32 |

| wolffd@0 | 34 Example |
| wolffd@0 | 35 </h2> |
| wolffd@0 | 36 <PRE> |
| wolffd@0 | 37 |
| wolffd@0 | 38 mdnmixes = mdnfwd(net, x); |
| wolffd@0 | 39 mixes = mdn2gmm(mdnmixes); |
| wolffd@0 | 40 p = gmmprob(mixes(1), y); |
| wolffd@0 | 41 </PRE> |
| wolffd@0 | 42 |
| wolffd@0 | 43 This creates an array GMM mixture models (one for each data point in |
| wolffd@0 | 44 <CODE>x</CODE>). The vector <CODE>p</CODE> is then filled with the conditional |
| wolffd@0 | 45 probabilities of the values <CODE>y</CODE> given <CODE>x(1,:)</CODE>. |
