| Abstract: | With the problem of the Hu’s method,an improved discernibility matrix and the computation of the core is put forward in this paper,and the correctness of this method is proved.This method not only overcomes the drawbacks of the Hu’s method,but also reveals the basic reason of error occuring in the Hu’s method. |
