    %ONES   Ones array.
%   ONES(N) is an N-by-N matrix of ones.
%
%   ONES(M,N) or ONES([M,N]) is an M-by-N matrix of ones.
%
%   ONES(M,N,P,...) or ONES([M N P ...]) is an M-by-N-by-P-by-... array of
%   ones.
%
%   ONES(SIZE(A)) is the same size as A and all ones.
%
%   ONES with no arguments is the scalar 1.
%
%   ONES(..., CLASSNAME) is an array of ones of class specified by the 
%   string CLASSNAME.
%
%   ONES(..., 'like', Y) is an array of ones with the same data type, sparsity,
%   and complexity (real or complex) as the numeric variable Y.
%
%   Note: The size inputs M, N, and P... should be nonnegative integers. 
%   Negative integers are treated as 0.
%
%   Example:
%      x = ones(2,3,'int8');
