水声通信中海洋对水声信号的吸收仿真，参考较完整模型Francois R E, Garrison G R，包含对陆地无线电吸收对比(Underwater acoustic communication in ocean water to absorb the sound signal simulation, a more complete model reference Francois RE, Garrison GR, contains terrestrial radio absorption contrast)

三电平逆变器SVPWM仿真模型。包含LCL滤波器，模块功能清晰。(Three- level inverter SVPWM simulation model. Contains LCL filter, module function is clear.)

D2D IoT and the code of multi cell equation will be detailled intthis section

利用MATLAB GUI设计实现图像处理的图形用户界面，利用MATLAB图像处理工具箱实现以下的图像处理功能： 1. 采用matlab Guide设计实现图像界面与按钮界面。 2. 连接摄像头，编写MATLAB初始化程序 3. 用摄像头采集一副图像，并能实现保存（使用控件按钮保存）。 4. 设计按钮实现对图像进行任意的亮度和对比度变化调整，显示和对比度变化前后的图像。 5. 设计按钮实现用户能够用鼠标选取图像感兴趣区域，显示和保存该选择区域。 (Designed and implemented using MATLAB GUI graphical user interface, image processing, using MATLAB image processing toolbox of image processing functions to achieve the following: 1. Designed to achieve an image using matlab Guide button interface with the interface. 2 Connect the camera to write MATLAB initialization procedure 3, with the camera capture an image and save to achieve (using the control button to save). 4 Design button on the image to achieve any change in the brightness and contrast adjustment, display, and contrast changes before and after images. 5 button design to achieve the user to select an image region of interest with the mouse, display and save the selected area.)

这个程序是用改进平方根法对线性方程组进行求解，要求系数矩阵必须是对称正定矩阵(This procedure is used to improve the square root method to solve linear equations, requiring the coefficient matrix must be symmetric positive definite matrix)

采用matlab工作环境，利用Thompson Tau进行异常值剔除(Remove outliers from data using the Thompson Tau method.)
