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.
