1function C = all (G, option)
2%ALL True if all elements of a GraphBLAS matrix are nonzero or true.
3% C = all (G) is true if all entries in G are nonzero or true.  If G is a
4% matrix, C is a row vector with C(j) = all (G (:,j)).
5%
6% C = all (G, 'all') is a scalar, true if all entries G are nonzero or true
7% C = all (G, 1) is a row vector with C(j) = all (G (:,j))
8% C = all (G, 2) is a column vector with C(i) = all (G (i,:))
