function [varargout] = eye(varargin)
%EYE Identity matrix.
%   EYE(N) is the N-by-N identity matrix.
%
%   EYE(M,N) or EYE([M,N]) is an M-by-N matrix with 1's on
%   the diagonal and zeros elsewhere.
%
%   EYE(SIZE(A)) is the same size as A.
%
%   EYE with no arguments is the scalar 1.
%
%   EYE(M,N,CLASSNAME) or EYE([M,N],CLASSNAME) is an M-by-N matrix with 1's
%   of class CLASSNAME on the diagonal and zeros elsewhere.
%
%   Example:
%      x = eye(2,3,'int8');
