Matrix Property Based on Rough Sets Model on Cartesian Product Universes

LUO Lai-peng (School of Basic Sciences,East China Jiaotong University,Nanchang 330013,China)  
This paper aims at Rough sets model on double universes built on two approximation spaces of Pawlak Rough set.By introducing the matrix tools,some matrix operators are defined,and the matrix expression and its computation of the model about some basic concepts and the relation between sets are discussed.Some properties of matrix computation about the kind of rough sets in general case and variable precision case are obtained and proved.
