Abstract

Testing a matrix on copositivity is a topic of recent interest  and practical importance in optimization modeling. In this paper, we present a some constructive characterizations for a class of copositive matrices with certain spectral properties. The characterizations is based onto the orthogonal projection of the nonnegative orthant onto the subspace spanned by the eigenvectors of a given indefinite matrix. Moreover, we give a new necessary conditions for copositive matrices.
