<p>The entries of these matrices are either zero or one, depending on whether the relation represented is false or true for the row and column corresponding to compared objects. Working with such matrices involves the Boolean arithmetic with  and  An entry in the <a href="page.php?w=matrix_product">matrix product</a> of two logical matrices will be , then, only if the row and column multiplied have a corresponding . Thus the logical matrix of a composition of relations can be found by computing the matrix product of the matrices representing the</p><p>
