%X Based on matrix reduction algorithm for information system introduced by Guan, a new improved computational method of attribute reduction was presented. According to the characteristics of operation between matrixes, the computation was simplified by introducing only the concept of zero value. This method was proved to be equal to attribute reduction by discernable matrix. At last, the method was applied to complete decision table. Its correctness and effectiveness are shown in an example.
