| Abstract: |
| There have been many research on the sub-orthogonal matrix, however, researchers tend to focus on the computing properties and its relation to some other special matrices. In this article, the sub-orthogonal matrix is studied from the structure of its elements;and three necessary and sufficient conditions are given. |
