%X80 Handwritten character dataset, 45 objects with 8 features in 3 classes
%
%	A = X80
%
% DESCRIPTION
% Load the dataset in A. This is the 80X dataset, having 3 classes.
% The 8 features are the distances from a bounding box to the 
% pixels of a set of handwritten characters 'X', '8' and '0', measured from
% the corners along the diagonals and from the edge midpoints along the 
% horizontal and vertical central axes.
