说明：  C语言编程实现D算法。本实验利用Matlab实现。实现以下功能： 1输入必要参数，包括：节点个数、节点间路径长度、给定节点； 2输出给定节点到其它各节点的最短路径、径长； 3节点间路径长度用矩阵形式表示：
(D C language programming algorithm. In this study, by Matlab. Achieve the following functions: 1 Enter the required parameters, including: the number of nodes, the path length between nodes, for a given node 2 output for a given node to other nodes of the shortest path, path length 3 path length between nodes in a matrix form:)
