摘要：
A technique is proposed to identify positive definiteness and positive semidefniteness of a real symmetric matrix using shifted power method. It is based on Gerschgorin theorem. The approach does not require determination of all principal minors of determinant and also determination of all eigenvalues of a system matirix. It is useful in various control system problems.
