用MATLAB编写的另一个用于图像灰度处理的小程序，很经典的一个图像灰度处理小程序。(Prepared using MATLAB image processing and another for a small procedure, it is the classic image of a small program to deal with.)

MATLAB 计算三角定位，根据信号强度进行定位。(The MATLAB calculation triangulation, locate based on signal strength.)

改进的蚁群算法matlab程序，验证无误。(ant-system)

0-1整数规划有很广泛的应用背景，比如指派问题，背包问题等等，实际上TSP问题也是一个0-1问题，当然这些问题都是NP问题，对于规模较大的问题用穷举法是没有办法在可接受的时间内求得最优解的，本程序只不过是一个练习，得意之处是用递归法把所有解都排列出来。另：胡运权所著的《运筹学基础及应用（第三版）》第97页的例3，我用本程序求解得到的结果是：最优解是x*=(1,0, 0, 0, 0)，最优值是f(x*)=8，但书求得最优解是x*=(1,0, 1, 0, 0)，最优值是f(x*)=4，是不是书中写错了，请大家验证。以下是源程序，大家可以任意使用无版权问题，另外，如果大家有大规模的0-1规划的问题也希望提供给我，谢谢。变量个数至少是3个(0-1 Integer Programming is a very broad background, such as assignment, bags and so on. actually TSP is a 0-1, of course, these problems are NP, for larger problem with the law is not exhaustive approach in an acceptable time frame to obtain the optimal solution. this procedure is only one practice, farewell tour is the method used recursive all of the solutions to show. Another : Hu Yun-author of "operational research, and application base (third edition)" Article 97 of the three cases, I use this procedure to solve the result is : is the optimal solution x = (1,0, 0, 0, 0), the optimal values of f (x*) = 8, but the book is to find the optimum solution x = (1,0, 1, 0, 0), the optimal values of f (x*) = 4, the book is not a mistake, please certification.

利用信号自相关法，对给定参数的，夹杂高斯白噪声的随机信号进行检测。通过观察自相关函数图形来分析接受的随机信号中是否有余弦信号存在。(Autocorrelation method using the signal for a given parameter, mixed Gaussian white noise random signal is detected. By observing the autocorrelation function graph to analyze random signal received if there exists a cosine signal.)

说明：  用C语言编的关于粒子群的流程和代码，期待进一步验证(Made with C language on the particle swarm process and code, look forward to further verify)
