+%CONFFIG Display a confusion matrix.
+%
+%	Description
+%	CONFFIG(Y, T) displays the confusion matrix  and classification
+%	performance for the predictions mat{y} compared with the targets T.
+%	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 Y and T corresponds to a single example.
+%
+%	In the confusion matrix, the rows represent the true classes and the
+%	columns the predicted classes.
+%
+%	FH = CONFFIG(Y, T) also returns the figure handle FH which  can be
+%	used, for instance, to delete the figure when it is no longer needed.
