Let Ct be the ring of all polynomials in the real variable t with complex coef-ยฎcients. We show that if A is an n-square hermitian matrix with entries in R, then A is congruent to the direct sum of a zero matrix and a diagonally dominant matrix. Here, diagonally dominant means that the degree of any
