| Daniel@0 | 24 Description |
| Daniel@0 | 25 </h2> |
| Daniel@0 | 26 <CODE>conffig(y, t)</CODE> displays the confusion matrix |
| Daniel@0 | 27 and classification performance for the predictions mat{y} |
| Daniel@0 | 28 compared with the targets <CODE>t</CODE>. The data is assumed to be in a |
| Daniel@0 | 29 1-of-N encoding, unless there is just one column, when it is assumed to |
| Daniel@0 | 30 be a 2 class problem with a 0-1 encoding. Each row of <CODE>y</CODE> and <CODE>t</CODE> |
| Daniel@0 | 31 corresponds to a single example. |
| Daniel@0 | 32 |
| Daniel@0 | 33 <p>In the confusion matrix, the rows represent the true classes and the |
| Daniel@0 | 34 columns the predicted classes. |
| Daniel@0 | 35 |
| Daniel@0 | 36 <p><CODE>fh = conffig(y, t)</CODE> also returns the figure handle <CODE>fh</CODE> which |
| Daniel@0 | 37 can be used, for instance, to delete the figure when it is no longer needed. |
