用matlab实现二维情况下TM波在自由空间的的传播仿真，带有PML边界.很直观的！(realize the propogation of electromagnetic in TM mode under 2-D situation in free space，with respect to the PML ABC.)

优化设计中利用鲍威尔算法求解的优化算法的介绍(Optimal Design Algorithm for the use of Powell' s presentation of the optimization algorithm)

路径损耗，阴影，衰落（瑞利，莱斯和中头m）；信号的调制，解调和比特错误率（BER）与SNR曲线(The path loss, shadowing, fading (Rayleigh, Rice and Nakagami-m) signal modulation, demodulation and bit error rate (BER) and the SNR curve)

函数的近似式，构造函数的逼近方法，从而得到比较准确的函数图象(Is often necessary to obtain the function approximation constructor approximation method)

阵列信号处理的高分辨率估计，有CDF三角函数曲线/三维曲线图，能量熵的计算，Matlab实现界面友好，结合PCA的尺度不变特征变换(SIFT)算法，调试通过可以使用。( High-resolution array signal processing estimates, There CDF trigonometric curve/3D graphs, Energy entropy calculation, Matlab to achieve user-friendly, Combined with PCA scale invariant feature transform (SIFT) algorithm, Debugging can be used.)

说明：  基于遗传算法的排课表的代码，通过调试，可以使用，如果想做成系统，请自行完成工程文件，这里只是排课的代码。(Time-table of the code, debugging, you can use if you want to create, please complete the project on its own, only here Course Scheduling code.)

可见光通信系统中单点光源的均方根时延扩展的仿真源代码(DRMS in vsible light communication)

说明：  无人机路径规划，提出改进的A*算法，参考2019年研究生数学建模竞赛F题(UAV path planning, propose improved a * algorithm, refer to the f problem of 2019 graduate mathematical modeling competition)

先用gabor 小波滤波器,做特征提取，然后用支持向量机（SVM）做分类，来实现人脸检测.需要用matlab 2010 或更新的版本才能运行(the code is used for face detection.Firstly it use gabor wavelet filter for feature extraction,Secondly it use support vector machine (SVM）for classification.matlab 2010 required.)
