控制行业中重要的least square parameter solution，里面使用了一个例子，可以将输入改变然后使用-control of the most important sectors least square parameter solution , which use an example, we can then use the importation of change

weighted least square line extraction with original sensor data

　给定一个N*N 的方形网格，设其左上角为起点◎，坐标为（1，1），X 轴向右为正，Y 轴向下为正，每个方格边长为1。一辆汽车从起点◎出发驶向右下角终点▲，其坐标为（N， N）。在若干个网格交叉点处，设置了油库，可供汽车在行驶途中加油。汽车在行驶过程中应遵守如下规则： 　　求汽车从起点出发到达终点的一条所付费用最少的行驶路线。-Given an N* N square grid, set the upper left corner as a starting point ◎, c

It is one of the successful prediction algorithms to estimate frequently for unknown parameters with real time operation. The principle of Recursive Least Square depends on least square mathematical weighted. Also, Recursive Least Square can set the
