===Example===
The binary relation ''R'' on the set {{nowrap|{1, 2, 3, 4}{{null}}}} is defined so that ''aRb'' holds if and only if ''a'' [[divides]] ''b'' evenly, with no remainder. For example, 2''R''4 holds because 2 divides 4 without leaving a remainder, but 3''R''4 does not hold because when 3 divides 4, there is a remainder of 1. The following set is the set of pairs for which the relation ''R'' holds.
:{(1, 1), (1, 2), (1, 3), (1, 4), (2, 2), (2, 4), (3, 3), (4, 4)}.
The corresponding representation as a logical matrix is
:<math>\begin{pmatrix}
1 & 1 & 1 & 1 \\
0 & 1 & 0 & 1 \\
