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