中文说明：对某一评价系统进行离散化处理后，得到决策表，此程序是利用基于粗糙集正域对其进行属性约简，其中函数delrepeat-约去重复样本函数，calimport是求整个决策表的重要度函数，consistent是一致性检验函数，redu是删除矩阵阵列的函数，equvalue是求等价集函数，delrow是去掉整列函数，
English Description：
For an evaluation system is discretized, get the decision table, this program is the use of positive region attribute reduction based on rough set on it, where the function delrepeat- to duplicate sample function, Calimport is an important degree function for the whole of the decision table, consistent is a consistency check function, Redu is a function to delete a matrix array. Equvalue is the equivalent set function, delrow is to remove the entire column function,
