最小二乘法进行执行拟合小程序,只要输入一系列大于2个坐标点的数据,与matlab直线拟合结果做过比较,结果比较吻合和皮(The least square method carries on the execution fitting Mini Programs, as long as inputting a series of data larger than two coordinate points, has made the comparison with the matlab straight line fitting result, the result is quite consistent with the skin.)
