用matlab模拟光线在三棱镜中的轨迹，以及顶角与折射方向的关系(stimulated ray trace in triple prism )

说明：  顶点覆盖近似算法，本人已经运行过，可以使用(Vertex cover approximation algorithm, I have to run off, you can use)

本程序对一维信号能实现快速分数阶傅里叶变换，并附有注释(The program for one-dimensional signal can achieve fast fractional Fourier transform, together with comments)

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)

用MATLAB实现了多相滤波器的仿真，给大家提供个思路(Polyphase filter simulation with MATLAB)

EMD分解，用于处理数据，是自适应分解为若干个IMF分量，按照频率有小到大的顺序！(EMD decomposition is used to process the data, adaptive decomposed into several IMF components, in accordance with the frequency of small to large order!)

一个matlab的跟踪小例子，功能很简单，容易理解(A small example of the tracking matlab for beginners to use, very simple)

Mass spring damper model

用牛顿法计算简单电力系统潮流，可以计算任意节点的潮流。自动输出中间的相关结果，并且有清晰可以操作的界面(Newton s method with a simple power flow)

高压输电线的工频电场预测mathlab代码 最低高度11米对地1.5m的工频电场的预测(Power frequency electric field is calculated)
