For a positive integer n and for a real number s, let s n denote the set of all n × n real matrices whose rows and columns have sum s. In this note, by an explicit constructive method, we prove the following. (i) Given any real n-tuple = (λ 1 , λ 2 , . . . , λ n ) T , there exists a symmetric matri
