中文说明：基于RSSI的质心定位算法，matlab源代码，用到了norm函数循环求范数，并设阈值来调控，显示定位效果，并表示误差，质心定位的效果一般在节点密度越大越好，这也是定位算法的通病，如果可以设置加权就更好的。很好的代码，大家多多学习
English Description：
Centroid localization algorithm based on RSSI, MATLAB source code, used to ask norm the norm function cycle and threshold values established pursuant to regulation, display effect and said error, locating the center of mass General in node density effect of bigger is better, it is also location of defects, if you can set the weights better. Very good code, everyone can learn
