| Abstract: | It introduces the concept of two weighted sub-positive semi-definite matrices,which is an extension of weighted sub-positive semi-definite matrices.It deals with the relationship between two weighted sub-positive semi-definite matrices and weighted sub-positive semi-definite matrices,and gives a criteria for two weighted sub-positive semi-definite matrices. |
| Keywords: | sub-positive semi-definite matrices weighted sub-positive semi-definite matrices two weighted sub-positive semi-definite matrices |
