说明：  自编粒子滤波算法程序，可解决非线性非高斯条件下的目标跟踪问题。(PF written by myself which provided solution of target tracking with non-linear and non-gauss environment.)

matlab实现函数y=sin(pi*x)的二次平方逼近的脚本语言，(matlab to achieve the function y = sin (pi* x) approximation of the second square of the scripting language,)

使用蚁群算法进行TSP问题的求解，画出了初始城市分布，蚁群算法求得的路线图。(Using the Ant Colony Algorithm to solve the problem of Traveling Salesman Path.The initial distribution of the cities is presented.And the path for the salesman can be seen clearly from the figure.)

%solve u_xx + u_yy = f(x,y) % over the region D = [x0,xf,y0,yf] = {(x,y) |x0 <= x <= xf, y0 <= y <= yf} % with the boundary Conditions: % u(x0,y) = bx0(y), u(xf,y) = bxf(y) % u(x,y0) = by0(x), u(x,yf) = byf(x) % Mx = # of subintervals along x axis % My = # of subintervals along y axis % tol : error tolerance % MaxIter: the maximum # of iterations

matlab GUI 示例，利用guide命令。主要是说明了一下框架和用法。(matlab GUI example, the use of guide command. Is mainly explained about the framework and usage.)

学习连续时间信号和离散时间信号在MATLAB中的表示(Learning continuous-time signals and discrete-time signal representation in MATLAB,)

说明：  一种基于RSSI的DV-HOP加权算法，该算法基于节点接收信标节点位置元组时的信号强度（RSSI）对邻居节点间跳数进行加权处理，将节点间的跳数与距离相关联，仿真试验结果证明该加权算法可大大提高定位精度。( a RSSI based weighted DV-HOP (RWDV-HOP) Localization algorithm is presented. In this algorithm the hops of adjacent node is weighted by the RSS of flooding packets transmitted between adjacent node. Our algorithm improves the localization accuracy compared with previous algorithms, which has been demonstrated by the simulating results.)
