| 摘 要： | 集合与关系是离散数学中非常重要的内容,直接根据定义判定关系的六种性质是比较困难的,尤其是对传递性和反传递性的判定.本文通过引入矩阵的Hadmard乘积的定义分别给出了这六种性质的矩阵判定方法.

| Abstract: | Set and relation are very important in discrete mathematics.It is hard to judgement the six kinds of property of relation directly according to their definitions,especially for transmission property and anti-transmission property.In this paper,we propose matrix judgement methods of the six kinds of property of relation by introducing the definition of Hadmard product of matrix. |
