Abstract. Rough set theory was introduced by Pawlak in the early 1980's to deal with a vague description of objects. Rough sets allow for representing sets approximately in terms of the available context knowledge. The concept of approximation is one of the most fundamental in rough set theory. The purpose of this paper is to introduce the new structure called Rough Matrix Theory,we also making the basic notions in our new way of representations. Using this rough matrix we deal with a decision making theory.
