使用matlab搭建了一个直流稳压电源的模型，两级式，前级不控整流，后级升降压(A model of DC regulated power supply is built by using matlab. It is two-stage, with uncontrolled rectifier at the front stage and step-up and step-down at the back stage.)

实现费诺编码费诺编码输入为+7个信源符号,其概率分布为：(其中信源符号用A+B、、G表示)A_0.2++B_0.19++C_0.18++D_0.17++E_0.15++F_0.10++G_0.01然后输入程序中得到结果（详细文档，值得一下）-Fenaux Fenaux coding to achieve coding input+7 source symbols, the probability distribution as follows: (where source symbols with the A+ B,, G indicated) A_0.2++ B_0.19++ C_0.18++ D_0.17++ E_0.15++ F_0.10++ G_0.01 and then enter the program to get results (detailed documentation, it is worth it)

说明：  7.0版本以上UO脱机脚本，功能强大，非常好用，适合挂小号(Uo offline script above version 7.0, powerful, very easy to use, suitable for small size)

C# Ping命令窗口仿真，用C#与Windows相关编程知识，模拟仿真出Windows系统中的ping命令，界面和功能几乎是一样的，直接运行生成的exe文件，即可看到CMD Ping命令窗口。

自己用的Kalman滤波工具箱。包含52个m文件。绝对物有所值！(Own use of the Kalman filter toolbox. Containing 52 m files. Absolute value for money!)

说明：  汽车bai的7自由度模型du一般是在设计汽车悬架时用zhi到，1/4悬架时2自由度模型，包括簧上部分的dao垂直运动和簧下部分的垂直运动，半车悬架是4自由度模型，整车用7自由度模型。考虑汽车悬架作用，这车车身有三个自由度，分别是车体的Z轴上下运动，沿X轴和Y轴的转动。对于空间刚体6个自由度中的其他3个自由度，2个平动和转动与悬架系统无关，所以没有考虑。上述3个车身自由度加上4个悬架的簧下部分(主要是轮胎的上下跳动)，一共是7个自由度。(The 7-DOF model Du of automobile Bai is generally a 2-DOF model when designing automobile suspension, including the vertical movement of Dao on the spring part and the vertical movement of the under spring part. The half car suspension is a 4-DOF model, and the whole car is a 7-DOF model. Considering the function of automobile suspension, the car body has three degrees of freedom, which are the up and down movement of Z axis of the car body, and the rotation along X axis and Y axis. For the other three of the six degrees of freedom of the space rigid body, two translation and rotation are independent of the suspension system, so they are not considered. The above three body degrees of freedom plus the four suspension spring parts (mainly the up and down runout of tires), a total of 7 degrees of freedom.)

说明：  读取NDVI文件 基于月数据年平均合成处理 统计年均NDVI并绘制曲线 计算年际变化率 将结果保存为ENVI标准文件(Read the NDVI file Composite processing based on monthly data and annual average The average annual NDVI was calculated and the curves were plotted Calculate the interannual rate of change Save the results as an ENVI standard file)
