You need to download the general purpose toolbox and the signal toolbox. You need to unzip these toolboxes in your working directory, so that you have toolbox_general/ and toolbox_signal/ in your directory. -You need to download the general purpose toolbox and the signal toolbox.

本源程序提供在AWGN信道下的bpsk调制方式的仿真，并与理论曲线作比较，得到了理想的结果-This source provides bpsk under the AWGN channel modulation of the simulation, and compared with the theoretical curve obtained satisfactory results

[输入] 图的顶点个数N，图中顶点之间的关系及起点A和终点B [输出] 若A到B无路径，则输出“There is no path” 否则输出A到B路径上个顶点 [存储结构] 图采用邻接矩阵的方式存储。 [算法的基本思想] 采用广度优先搜索的方法，从顶点A开始，依次访问与A邻接的顶点VA1,VA2,...,VAK, 访问遍之后,若没有访问B，则继续访问与VA1邻接的顶点VA11,VA12,...,VA1M，再访问与VA2邻接顶点...，如此下去，直至找到B，最先到达B点的路径，一定是边数最少的路径。实现时采用队列记录被访问过的顶点。每次访问与队头顶点相邻接的顶点，然后将队头顶点从队列中删去。若队空，则说明到不存在通路。在访问顶点过程中，每次把当前顶点的序号作为与其邻接的未访问的顶点的前驱顶点记录下来，以便输出时回溯。 #include int number //队列类型 typedef struct{ int q[20] -[imported] map of the number of vertices N, Vertex map of the relationship between the starting point and end point A and B [output] if A to B without path then exporting "There is no path" Otherwise output A to B on the path vertices [storage structure] plan adopted adjacency matrix of storage. [Algorithm for the basic idea] BFS way from the vertex A, A visit followed with adjacent vertices VA1, VA2 ,..., VAK, visiting times, if not visit B, continue to visit with the VA1 adjacent vertices VA11, VA12 ,..., VA1M.

说明：  这是分割后的第二部分。本书的内容包括求解方程组、插值、微分方程及一系列。每章都有实例以帮助读者了解相关应用领域。并有一些matlab的代码，和题目的参考答案。(This is the second part after the split.The content of this book includes solving equations, interpolation, differential equations, and a series. Each chapter has examples to help readers understand the relevant application areas. And there are some matlab codes, and reference answers to the questions.)

一个有很多错误的问题，希望哪位高手可以帮我解决一下啊，记住要是高手啊，一般的手就不要下了．自食其力．-a lot of mistakes in the hope that any expert can help solve what I ah, remember if master ah, general hand had not. Self-reliance.
