与传统的小波分解相比，提升小波可以实现整数小波变换，其方法与一般去噪法相同，都是对小波分解的高频系数进行阈值量化来达到去噪的目的。(Compared with the traditional wavelet, lifting wavelet can achieve integer wavelet transform, its the same way as regular de-noising method, are the high-frequency coefficients of wavelet decomposition threshold quantization to achieve the purpose of de-noising.)

模糊PID程序,很好用的哦，快来下载，来把来吧(Fuzzy PID program, the good, oh, come download to the Come)

利用optisystem软件仿真半导体激光器的P-I特性曲线。得到的图形遵循在超过阈值电流之后，输出光功率与电流成线性关系规律。(Using software optisystem simulation P- I characteristics of semiconductor laser curve.The graphics follow after more than threshold current, a linear relationship with the output light power and current laws.)

说明：  Matlab课件PPT格式，介绍了Matlab的功能及使用，非常适合初学者。(Matlab courseware PPT format, introduced the use of Matlab functions and is suitable for beginners.)

股票指数模拟为几何布朗运动，GBM。 参数有五个： s0，dt（time step），均值，标准差，到期时间T； 利用子函数进行10万条轨道的monte carlo 模拟到期日（3个月）的指数点数，从而估计在买入信号出现后，3个月后的损益情况，主要用来估算VAR (Financial risk analysis on Matlab monte carlo simulation, stock index simulation for geometric Brownian motion, GBM. )

GNSS软件接收机，源自《软件定义的GPS和伽利略接收机》书中配套程序，做过修改，在原有程序框架下使用了2阶锁频环辅助3阶锁相环(The GNSS software receiver, derived from GPS and Galileo receiver of software defined supporting program in the book, modification, the original application framework use 2 order frequency locked loop aided third-order phase-locked loop )

采用改进PSO对含风光发电的微电网出力进行优化(Optimizing the output of microgrid with wind power generation by using improved PSO)

matlab 中矩阵行列移动函数 m文件，shiftl,shiftr等(matlab matrix of the ranks of mobile function m file, shiftl, shiftr such as)

surf特征点检测，并实现两幅图像特征点的匹配(surf feature point detection, and the two images matching feature points)

在MATLAB环境下，用FDTD方法，用高斯点源仿真TE波在空间的传输。(In the MATLAB environment, using FDTD method, the Gaussian point source simulation of the transmission of TE waves in space.)
