利用最小二乘方法对二维位置进行滤波算法的仿真-Least-squares fit of ellipse to 2D points

这是android的一个小项目，文件管理器，在ellipse开发的，供大家学习。-This is a small project, the android file manager, developed in the ellipse for all learning.

多雷达联合定位，通过距离矩阵形成椭圆，并求取交点完成定位(Multi-radar joint positioning, ellipse is formed by distance matrix, and intersection point is obtained to complete positioning.)
