中文摘要：
针对粗糙集中上、下近似集的求解问题,根据关系的矩阵表示和矩阵运算具有简便直观的特点,提出了一种利用关系矩阵和基本的矩阵运算计算上、下近似的方法,通过理论证明结果显示该方法是可行有效的。
英文摘要：
This paper mainly discussed the problem about the calculation of upper and lower approximations in rough set theory.Because a relation could be represented by a matrix and matrix operations were simple and intuitive,proposed a new method about the calculation of upper and lower approximations based on relation martix and martix operations.The theoretical proof shows that the method is feasible and effective.
