说明：  用函数graycoprops去检测图像灰度共生矩阵，该例子主要是应用于图像纹理检测(Use function graycoprops to check picture ,it is very good )

说明：  经典浓度聚类算法DBSCAN的MATLAB实现，简单易懂，可以运行(Classical clustering algorithm DBSCAN concentration of MATLAB implementation, easy to understand, you can run)

逆合成孔径雷达，距离多普勒算法下的多点目标欺骗干扰，Matlab语言仿真(Range_Dopplor algorithm of deception jamming about Inverse Synthetic Aperture Radar )

Chess Application developed in C# for academic purposes. We have implemented a function created by us. Though, it has some troubles.

本书罗列了许多在数学建模中用到的代码，尤其在竞赛时，作用很大。赶快下载吧。(The book lists many of the mathematical modeling used in the code, especially in the race, play a great role. To download it.)

该压缩包的程序实现对图像的边缘进行检测，并且对图像进行阈值分割。源码全部为自己编写，效果不错。不知道上传matlab的源码能不能开通会员，所有上传的都是自己的代码，虽然有些简单但是都是自己的劳动，刚起步，希望和大家交流。(of the compressed image program to the brink for testing and the right image thresholding segmentation. Source for all the preparation work to be done. Upload Matlab do not know the source can open membership, are all uploaded the code, Although some are simple but their work has just started, and we hope that the exchanges.)
