A lonesum matrix is a (0, 1)-matrix that is uniquely determined by its row and column sum vectors. In this paper, we introduce lonesum decomposable matrices and study their properties. We provide a necessary and sufficient condition for a matrix A to be lonesum decomposable, and give a generating function for the number D k (m, n) of m× n lonesum decomposable matrices of order k. Moreover, by using this generating function we prove some congruences for D k (m, n) modulo a prime.
