神经网络模型权重系数判定用的代码，back propagation(Code neural network model of weight coefficient determination, back propagation)

基于LMS的双向回波削除源码，不过回波幅度不要大于0.2,否则算法认为DOUBLE TALK DETECT。各位可修改此阀值，试试效果(based on the two-way LMS Echo slashing source, but not greater than the rate Echo 0.2, or that the algorithm** DOUBLE TALK. You can modify this threshold, try Effect)

动态硅环仿真程序 主要用于模拟硅环的谐振特性以及双光子吸收效应，非线性的动态过程。(silicon resonator dynamic simulation)

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)

基于MATLAB串口数据采集系统及滤波源码，可以运行(Based on MATLAB serial data collection )
