+Description
+</h2>
+<CODE>[C, rate] = confmat(y, t)</CODE> computes the confusion matrix <CODE>C</CODE>
+and classification performance <CODE>rate</CODE> for the predictions mat{y}
+compared with the targets <CODE>t</CODE>.  The data is assumed to be in a
+1-of-N encoding, unless there is just one column, when it is assumed to
+be a 2 class problem with a 0-1 encoding.  Each row of <CODE>y</CODE> and <CODE>t</CODE>
+corresponds to a single example.
+
+<p>In the confusion matrix, the rows represent the true classes and the 
+columns the predicted classes.  The vector <CODE>rate</CODE> has two entries:
+the percentage of correct classifications and the total number of
+correct classifications.
