## Arguments are advanced to point out that simpliJicatio?L analogous to that in the computational test for positice definiteness of multidimensional Hermitian matrices is not possible when the Hermitian matrix is to be tested for non-negative de&items-s.

Let A be an n x n matrix with non-negative entries and no entry in (0, 1). We prove that there exist integers r, s with 0 <~ r < s ~< 2" such that A" <~ AL We prove that 2" cannot be replaced with e~. We also give an application to the theory of formal languages.
In this paper a modification of the standard algorithm for non-negativity-constrained linear least squares regression is proposed. The algorithm is specifically designed for use in multiway decomposition methods such as PARAFAC and N-mode principal component analysis. In those methods the typical si
