先进PID，在MATLAB环境下编程，便于初学者进行交流，不足之处还望指导。(Advanced PID, in the MATLAB programming environment, easy for beginners to communicate, less than the guidance of the Office also hope.)

三次样条曲线，可以根据不同条件进行选择，包括边界条件等(Cubic spline curve can be selected according to different conditions)

求频率响应的程序，里面提供了三个求的方法，经过本人调试(frequency response)

PROGRAM GENERATES RANDOMLY LOCATED BALLS WITHIN A CIRCULAR

说明：  使用遗传算法优化36单元圆形天线阵列,有需要的可以分享一下(optimise the 36 elements of antena arrays)

说明：  使用ziegler方法，对PID控制器进行PID整定。(Using Ziegler method, the PID controller is tuned.)

这个程序主要是用来设计实现一个加解密的系统 采用matlab设计 用了二进制循环 异或的知识(This program is mainly used to design and implement a system of encryption and decryption using matlab design cycle using the binary XOR of knowledge)

sparsity preserving projections (SPP)方法，根据论文《sparsity preserving projections with applications to face recognition》使用AR人脸数据库(sparsity preserving projections (SPP)method, according to the paper "sparsity preserving projections with applications to face recognition", using the AR face image database)

FHSS_DSSS_CDMA的m文件，可以在matlab的simulink上仿真~(FHSS_DSSS_CDMA the m file )

This program simulation Rayleigh channel and Magnitude of fft of a single realisation of X(t) and Calculating the central moments and beta values for in and quadrature phase.
