说明：  pso算法的matlab实现中有很多共同点，该工具箱对一些共性建立函数，以后可以直接调用(The Tool Box)

matlab实现图上需找最短路径的迪杰斯特拉算法，寻找任一点和其他点之间的最短距离，最终结果为最短路径度量矩阵和正序路由矩阵(matlab implementation on the map to find the shortest path Dijkstra algorithm to find the shortest distance between any point and other points, the final result is the shortest path metric matrix and positive sequence routing matrix)

These codes are to implement the link of free space optics.

说明：  模拟退火算法来源于固体退火原理，是一种基于概率的算法，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。(Simulated annealing algorithm is derived from the principle of solid annealing is a kind of algorithm based on probability, high solid heating to fully, then let it slowly cooling, heating, inside the solid particles with the temperature rise to disorder, internal energy increase, and slowly cooling particles become more orderly, and in each temperature to reach the equilibrium state, finally reach the ground state in normal temperature, can reduce to a minimum.)

选取读入一份彩色图像，在运行Untitled.m程序时：先用鼠标交互的选取一个颜色区域作为你要与其他色彩分割的目标，，鼠标选取好后，按ENTER健后出现进行分割出现结果。 (Select a color image read in the run Untitled.m program: the first interaction with the mouse, select a color region as the color you want to split with other goals, the mouse selection is completed, press ENTER health appeared after the results of segmentation .)

本程序模拟一个机器人躲避障碍的仿真.其中有不完善的地方 迫于精力有限,具体过程还有点粗糙,读者可以加以修正 (a simulation of the robot avoid obstacles to the simulation. Which forced the inadequacies in the energy are limited, There is a process in concrete rough, and readers can be amended)

在车辆检测中，对前景引入一个滤波函数，基于此函数对阴影进行消除。(In vehicle detection, the future introduction of a filtering function, based on this function to eliminate shadows.)

大规模MIMO信道仿真 多发多收 单发单收等等等等等等。。。(Massive ＭＩＭＯ)

LDA的matlab实现，得出alpaha和beta的值(the procedure to implement Latent Dirichlet Allocation ,the end of this procedure is the value of alpha and beta.)

C3P0连接池配置时依赖的一个包,c3p0-0,9,2,1,jar我也上传了(C3P0 connection pool configuration when relying on a bag, C3P0,9,2,1 0, I also upload the jar)
