用rayleighchan 函数仿真时要注意最后要做相位补偿（此问题是导师发现的） 程序步骤： ~产生随机序列 ~产生瑞利信道 ~调制 ~记忆信道特征 ~信号通过信道 ~相位补偿 ~加高斯噪声 ~解调 ~计算仿真误比特率 ~计算理论误比特率 ~不同颜色画出误比特率曲线对比(Function Simulation with rayleighchan last thing to note when the phase compensation (this issue is found mentor) program steps: ~ ~ generated random sequence modulation in Rayleigh Road, ~ ~ ~ memory characteristics of the signal channel by channel ~ ~ plus Gaussian noise phase compensation ~ ~ demodulation bit error rate calculation simulation of bit error rate calculation theory ~ ~ different colors to draw curves of bit error rate)

说明：  Matlab编程手册，一些编程的问题基本都能在这解决。(Matlab programming manual, some basic programming issues to resolve in this can.)

2012年研究生数学建模大赛 D题 第一问 地球的显示的代码 MATLAB代码(Graduate Mathematical Modeling Contest D Earth in question first asked in 2012 the code displayed MATLAB code)

Model : PM42L-048-HHC9 Drive Mode : BIPOLAR CHOPPER Drive Voltage : 24.0 V Method : 2-2P Drive IC : UDN2917EB Surge/Current : / 600 mA / Phase (Peak) Coil Resistance : 7.0 Ω Magnet Material : MS70M

此matlab程序用于电力系统低频减载的分析处理，包含功率缺额计算以及电压的计算(aim at the analysis of the power system UFLS)

这是一个信号处理很好例子，里面三角波，阶跃信号，以及方波信号的处理，有各种变换，同时也有gui方面的参考，代码能作参考，对小白很友好！(This is a good example of signal processing, triangle wave, step signal, and square wave signal processing, there are various transformations, but also GUI reference, code can be used for reference, very friendly to white!)

激光光束在介质中传播的分析及仿真，可仿真光束传输特性，程序运行结果较为直观，(Laser beam propagation in the medium analysis and simulation, the beam transmission characteristics can be simulated, the program operating results are more intuitive,)

求第一个城市到其它城市的最短路径.用矩阵（为顶点个数）存放各边权的邻接矩阵，行向量、、、分别用来存放标号信息、标号顶点顺序、标号顶点索引、最短通路的值(The first city to find the shortest path to other cities. With a matrix (for the number of vertices) records of the right side of the adjacency matrix, row vector, were used to store label information and label the vertex order, label the vertex indexes, the shortest pathway value)
