升cosine窗加权的波束方向图：N=11(Raised cosine weighting function)

说明：  很经典的emd程序，可以运行使用，法国学者编写(It is a classic EMD program, which can be run using)

计算长周期光纤光栅的纤芯基膜的有效折射率的程序，很基本(Calculation of long period fiber grating effective refractive index of core-based film program, very basic)

基8-DFT计算，每8点为一蝶形运算单元，4096点计算效率较基2-DFT提高50 (Yl 8-DFT calculation, every 8 points for a butterfly operation unit, the 4096-point computation efficiency than the base 2-DFT increased by 50 )

说明：  用matlab实现clockr仿真，初学试用的小程序(Clock of matlab simulation, a small trial program beginner)

This code is to find data distribution of wind speed. The Weibull distribution parameters are determined

用相似性方法做的特征点的匹配，比较了SSD与SAD方法的各自效果。(feature points matching method used by the similarity, and comparing the respective effects of the SSD and SAD methods.)

王丰华等提出的相位差分法的实现，主要用于信号处理中提取信号的瞬时频率。注意该方法只适用于单分量信号。另外一个是利用自相关法求瞬时频率(Wang Fenghua such as the phase difference method to achieve, mainly used for signal processing to extract the instantaneous frequency of the signal. Note that this method is only applicable to single-component signal)

基于内容的图像信息检索，主要采用小波纹理的方法进行检索。(Content-based image retrieval, mainly using Wavelet texture method to retrieve.)
