SIFT特征匹配算法是目前国内外特征点匹配研究领域的热点与难点，其匹配能力较强，可以处理两幅图像之间发生的平移、旋转情况下的匹配问题(SIFT features matching algorithm is the hot matching algorithm of feature points at home and abroad . its matching ability is strong.It can match the feature points of two images which are rotated or traslation.)

K均值聚类是模式识别中非常重要的一种方法，通过K均值聚类可以将具有相同属性的元素进行聚合。(K-means clustering is a very important one in the pattern recognition method, polymerization by K-means clustering with the elements of the same property.)

说明：  雷达模拟程序，图像界面，在不同版本的MATLAB运行时需要调试。(Radar simulation program, image interface, need to be debugged in different versions of MATLAB.)

经典的功率谱和 双谱估计，很好，看看能用上的。(Classic power spectrum and dual spectrum estimation, well, look at can be used on.)

DCT- discrete cosine transform. compression ratio and psnr value are calculated

纵向罗绮光栅的制作。用于生成周期为6个（可以根据需要改变）像素的纵向罗绮光栅，可以根据需要设定光栅的分辨率。(Vertical Luo Qi Grating. Used to generate a period of 6 (can be changed) pixels vertically Luo Qi grating may be based on need to set raster resolution.)

国外人编写的一个分数阶系统的控制工具箱，可以设计分数阶控制器，评价系统性能(Abroad were prepared by a fractional order systems control toolbox, can be designed fractional order controllers, evaluation of system performance)

说明：  随机共振的弱信号检测，运用朗格万方程进行MATLAB的仿真(stochasitc resouance using for detecting the weaken signals,based on longawan function)
