Note on the Generalized Positive Definite Matrices |
| |
| Abstract: | It is useful and interesting to generalize the symmetric positive definite matrix. Several im- portant classes of these generalized positive definite matrices are defined and investigated in 1], 4]and 5]. In this paper we shall discuss proper inclusion relations between all these class of generalized positive definite matrices; study the equivalent condition for a real square matrix to belong to one of the classes;and point out wrong results in 4] and also in 5]. |
