Abstract: The paper builds the relationship of attribute set, Boolean matrix and logic equation set. And based on it, the Boolean matrixpresentation of rough set concept and operation is given. At last, the paper proves the equivalence of the attribute reduction under the presentation ofBoolean matrix and algebra.
