problems of optical communications

this code is face detection with malab with demo

倍频程计算，在振动或噪声技术应用中经常用到的算法程序，是matlab源码(octave, the vibration or noise technology applications often use the algorithm process, the source Matlab)

混沌与分形的程序.比较简单,但是还是源码的说.(Chaos and Fractal procedures. Relatively simple, but still the source said.)

基于机器学习方法的脑电信号自动分类研究 基于机器学习方法的脑电信号自动分类研究(Automatic classification based on machine learning method of eeg signals)

最小方差响应不变波束形成器即MVDR是一种高分辨谱估计方法，MVDR在信号处理DOA中应用较广。(Minimum variance beamformer response constant MVDR is a kind of high resolution spectrum estimation method in signal processing, MVDR DOA has a wide application)

正确率可以达到98％，仿真图是速度、距离、幅度三维图像，这是第二能量熵的matlab代码。( Accuracy can reach 98 , FIG simulation speed, distance, amplitude three-dimensional image, This is the second energy entropy matlab code.)

说明：  运用退火算法解决公共场合人流量问题，一次解决关于人员疏散相关问题(Applying annealing algorithm to solve the traffic problem in public places)

原始lmd算法，效果很不好，不知道程序哪里写错,不太能运行，自己做修改，但是上面的算法比较明确(The original LMD algorithm, the effect is very bad, I don t know where the program is misspelled,but it really can not run.If you want run it,just change a little.Actally the algorithm is clear.)

说明：  清空环境变量 网络结构建立 遗传算法参数初始化 迭代求解最佳初始阀值和权值 遗传算法结果分析 把最优初始阀值权值赋予网络预测 BP网络训练 BP网络预测 清空环境变量(Empty the environment variable Established network structure Genetic algorithm parameter initialization Iterative Solution optimum initial thresholds and weights Analysis of Genetic Algorithms The optimal initial threshold value is assigned to the right network prediction BP network training BP network prediction Empty the environment variable)
