讨论弦振动方程。一个标准弦振动方程，用于物理学和力学的上的振动讨论。通过mathematica 编程。（开发环境无mathematica，选择了接近的matlab）(Discuss a vibration equation. A standard vibration equation, using for mechanical purpose.)

这是一个异步电机无速度传感器的矢量控制仿真模型，其中转速辨识用的是模型参考自适应法。(This is an asynchronous motor vector control without speed sensor simulation model, which is used to identify the speed model reference adaptive method.)

用MATLAB还原一篇论文中的滑模观测器设计，含论文(Using MATLAB to Restore a Sliding-Mode Observer Design in a Paper with Papers)

说明：  本程序搭建了七电平MMC拓扑，并附有简单的控制策略，该程序可以运行，如果想研究MMC控制的可以学习，后期再次基础之上可以拓展为多端柔性直流输电系统。(This program builds a seven level MMC topology with simple control strategy. The program can run. If you want to study the MMC control, it can be extended to multi terminal flexible DC transmission system.)

C=CURVEFIT( 拟合模型 ,参数C初值,X数据,Y数据) 求参数C使得 sum {(FUN(C,X数据)-Y数据).^2}最小化(C = CURVEFIT ( fitting model and parameter C, initial X, Y data) for data parameters that sum {there (C) (C, X-ray data- Y j ^ 2) minimizing})

说明：  双曲型方程组的理论基础，包括守恒型方程组、非守恒型方程组的理论基础(The theory of hyperbolic basis, including the conservation equations, equations of non-conservative theory)

用于人脸识别的NMF分解程序，用MATLAB编写的(face recognition for the NMF decomposition process, the preparation of MATLAB)

Motion-Compensated Frame Interpolation (MCFI) is a technique used extensively for increasing the temporal frequency of a video sequence. In order to obtain a high quality interpolation, the motion field between frames must be wellestimated. However, many current techniques for determining the motion are prone to errors in occlusion regions, as well as regions with repetitive structure

小波包分析提取振动信号中的特征频率，电力系统暂态稳定程序，可以进行暂态稳定计算,计算时间和二维直方图。( Wavelet packet analysis to extract vibration signal characteristic frequency, Power System Transient Stability Program, can be transient stability, Computing time and two-dimensional histogram.)
