function C = ones (varargin)
%GRB.ONES a matrix with all ones.
%
% C = GrB.ones (n) ; n-by-n GrB double matrix of all ones.
% C = GrB.ones (m,n) ; m-by-n GrB double matrix of all ones.
% C = GrB.ones ([m,n]) ; m-by-n GrB double matrix of all ones.
% C = GrB.ones (..., type) ; matrix of all ones of given type.
% C = GrB.ones (..., 'like', G) ; matrix of all ones, same type as G.
%
% The memory required to store C is O(1) not O(m*n), so both m and
% n can be as large as 2^60.
