OptimalControl

说明：  draw a signal with its envelope

采用smith预估计对pid控制进行优化，可以达到很好的控制效果哦(Estimated using pre-smith optimized for pid control, can achieve good control effect oh)

本程序是关于光学双缝衍射的matlab仿真实验。(IN this text,you can run it in matlab directly.Optical double slit diffraction of matlab simulation)

矩形谐振腔中TEmnp模的场分布，matlab程序，改变程序中mnp可得到不同模式的场分布，结果正确(Matlab program of the field distribution of TEmnp in the rectangular resonant cavity, change the MNP value in the program can get the result of different mode field distribution, and the result is correctthe field distribution of TEmnp in the rectangular resonant cavity, the MNP value in the program can get the correct result of different mode field distribution)

通过应用于小波变换到lena.jpg图像，简单实现图像压缩，实现一级压缩和二级压缩(Through applied wavelet transform to lena.jpg image, a simple image compression, compression and two compression to achieve a)

EKF算法在MATLAB中的仿真及其分析比较(EKF algorithm in MATLAB simulation and analysis)

这是我自己编的一个MIMO 的仿真代码，很简单，仿真信道响应，可以参考一下。(This is my own compilation of a MIMO simulation code is very simple simulation of the channel response for reference.)

关于FFT的MATLAB代码，可以很直观的验证并得到FFT序列(The MATLAB code on the FFT, it is intuitive and FFT test sequence)

读取以.dat的数据文件；读取以MIT-BIH数据库的212格式文件(Read the MIT-BIH database 212 format data)

matlab 代码，主要用于计算一数据矩阵的标准差，方差，变异系数，话三维曲面图(matlab code, data matrix used to calculate a standard deviation, variance, coefficient of variation, then D surface chart)
