The main objective of the paper is to propose a matrix computation approach about Rough set module and discuss its properties. Some basic concepts such as class matrix operator, relation matrix operator and set matrix are introduced. Some results of the method are obtained. The relationships between matrix compution and including degree are discussed. These results are meaningful both in the theory and algorithm designed for Rough Set.
