计算任意层数平板波导结构。其中slabexec为主程序，readme中有程序使用的详细说明。可以计算任意层数的平板波导结构的有效折射率，光场分布和远场分布(PhotonicCrystals )

说明：  利用反步法实现路径跟踪，包括直线、椭圆，圆轨迹等(Path backtracking with backstepping)

比较专业的PID控制器，主要实现了以下几种常用的理论：Ziegler&Nichols、Cohen Coon、Reglabilite、IMC、Optimiszation、De Crite、PID1、PID2 (Comparison of professional PID controller, the main achievement of the following types of theories commonly used: Ziegler & Nichols, Cohen Coon, Reglabilite, IMC, Optimiszation, De Crite, PID1, PID2)

OFDM系统仿真，简单的OFDM基本框架的一个仿真，matlab环境下实现的(it is good！)

连续相位信号调制解调，CPM全响应信号调制解调( Continuous phase signal modulation and demodulation, CPM full response signal modulation and demodulation)

基于形态学的图像分割，MATLAB实现，先进行灰度变换。(Image segmentation, morphology based on MATLAB implementation, the first gray-scale transformation. )
