matlab程序设计教程源代码，很不错的，都是代码。是学习MATLAB，提高都受能力的参考资料(MATLAB codes)

很多种算法！！！解压了您能看到！很全面！ 此文件夹中的文件，如需被利用，则要直接放至work目录下 “最短路径”中的程序为一个网友写的，我把它改编为函数，放在“最短路和次短路中”，与次短路的程序并列，因为要求次短路，首先要求出最短路。 (A variety of algorithms! ! ! Extract you can see! Very comprehensive! This file in the folder, For use, will have to be directly released to the work directory Program in the "shortest path" for a net friend, and I adapted it to function on most short-circuit and short circuit in the "tied to short-circuit, the procedures to the requirements of times short-circuit, the shortest path first asked. )
