用于matlab的无线传感器网络时间同步算法的编程参考(Programming reference of time synchronization algorithm for wireless sensor networks in MATLAB.)

该源代码详细介绍了有关二叉树的所有相关操作(The source code details all related operations on the two fork tree.)

文件为stm32的ＳＤ接口操作，该程序演示ＳＴＭ３２的ＳＤ卡操作流程-Documents stm32 the SD interface operation, the program of the SD card STM32 demo operational processes

这也是学校的参赛项目并最后获奖的作品，其效果和小时候玩的平图板一样，非常耐玩，强烈推荐。-This is also the school

GIS数据，基于DEM的中国流域shapefile，可直接使用(GIS data, shape file based on DEM in China watershed, can be used directly .)

说明：  基于粒子群算法解决tsp旅行商问题，粒子群算法（以下简称PSO）就是模拟鸟群觅食行为的一种彷生算法 。 解=粒子=鸟 (鸟的位置象征着离食物的距离，粒子的位置也象征着离最优解的距离，是评价解质量的唯一标准)， 找食物=找最优解，一个西瓜=一个粒子找到的历史最优解，一块肉=整个粒子群找到历史最优解 。(Solving TSP traveling salesman problem based on particle swarm optimization)

说明：  用牛顿-拉夫森法求解非线性弹簧问题，用Matlab软件制作了一个简单的程序。(Use the Newton-Raphson method to solve the nonlinear spring problem,a simple program is produced by using the Matlab software.)

本压缩包里有计算关联维数的Matlab程序设计，较快。(compression of the bundle is calculated correlation dimension of the Matlab programming, faster.)
