在上传的资料‘tulun’中，PPT详细介绍了图论中的基本概念，并且给出了相应程序的算法，另外附有最短路Floyd算法的源程序和dijkstra的源程序。有利于在建模过程中利用MATLAB求解图论的相关问题。-PPT paper introduces the basic concepts of graph theory, algorithms and gives the corresponding program.Floyd also accompanied by the shortest road and the Dijkstra algorithm source program source program.n favour of the modeling process using MATLAB to solve the related problems of graph theory.
