function fh=conffig(y, t)%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.%%	See also%	CONFMAT, DEMTRAIN%%	Copyright (c) Ian T Nabney (1996-2001)[C, rate] = confmat(y, t);fh = figure('Name', 'Confusion matrix', ...
