Abstract: An operator--in general nonlinear--associated with a pair of non-negative matrices, is defined and some of its spectral properties studied. If the pair of matrices are a square matrix *A* and the identity matrix of the same order, the operator reduces to the linear operator *A*. The results obtained include generalizations of one of the principal conclusions of the theorem of Perron-Frobenius.
