说明：  偶图最大匹配完全照算法说明利用集合运算实现的matlab代码。这里需要大家讨论的是增广路的选取的算法，希望朋友们多多讨论，争取找一种更好的增广路方法，有想法的一定告诉我，谢谢，jxrhhu@hhu.edu.cn(Bipartite graph maximum matching algorithm description completely according to the use of computing to achieve a collection of matlab code. Here we need to discuss is the way to broaden the selection of the algorithm, a lot of friends who wish to discussions in order to find a better way to broaden the way, there is a certain mind to tell me, thank you, jxrhhu@hhu.edu.cn)
