说明：  用C语言实现最短路径算法中的Floyd-Warshall算法，这个算法可以用来解决信号处理中的一些问题。floyd_warshall.c是源程序；distance_2.txt文件存放图中各点之间的距离，以99999表示无穷大；floyd.txt文件是输出文件，其中存放各轮得到的输出矩阵，以及最后得到的各点间最短距离，如果有负回路则返回FALSE。
(C language shortest path algorithm of Floyd-Warshall algorithm, The algorithm can be used to solve signal processing some of the problems. Floyd_warshall.c yes source; distance_2.txt document storage map of the distance between points, 99,999 said to infinity; floyd.txt document output files, which kept the round of the output matrix, and finally come to the point of the shortest distance, If there is a negative loop it returns FALSE.)
