该程序很好解决了，将两个矩阵交叉相加的结果取出，直接相加的结果所对应的行省略. 另外一个是DOA估计的程序。(It is good for solving the two matrix for cross adding,and delete the direct adding.)

说明：  经典leach算法，和PSO算法，有想法的同学可以融合在一起，便于对比仿真。亲测有效(Classic LEACH algorithm, PSO algorithm, students with ideas can be fused together, easy to compare simulation. Pro test is effective)

说明：  用Matlab实现中值滤波，均值滤波以及高斯滤波(Using Matlab to achieve median filter, mean filter and Gaussian filter)
