一共有RecuCal.m LockMap.m BuildMatrix.m Edmonds.m GUI1.m 这几个文件，我把它们合到一块粘上去了,你再把他们分开保存就可以了.其中前三个文件都是为建立邻接矩阵服务的，Edmonds.m是匈牙利算法的主文件，GUI1.m只是调用Edmonds.m做个界面而已。

调用关系是GUI1.m调用Edmonds.m；Edmonds.m调用BuildMatrix.m和LockMap.m ；LockMap.m调用RecuCal.m最后运行GUI1.m就ok了#LockMap.mfunction [LMA, LMB] = LockMap(n, m)% LOCKMAP - 求解满足条件锁并设置相应的映射% 输入参数:n 表槽数,m 表高度数。

% 输出参数:LMA,LMB 分别为二维矩阵表示自然数到满足条件锁之间的映射。
