最小二乘法的例程,可以对数据进行线性拟合.由于源码较短只能进行直线拟合,曲线拟合的源码我稍后上传.-least squares method of programming, with the linear data fitting. As the only source for a shorter fitted to a straight line Curve fitting, I later upload source.

用最小二乘法来进行函数模拟。对输入的数据构造一个多项式。-using the method of least squares to function simulation. Of input data structure a polynomial.

研究各种拟合圆的方法,提出了一个圆的代数距离表示法的系数约束条件,在此约束条件下讨论圆的几何特征参数的估计问题,并给出了特征参数在约束条件下的最小二乘估计.实例验证表明,文中算法比一般最小二乘法具有更高的拟合精度. -Various methods of fitting a circle, a circle is proposed algebraic representation of the coefficient of distance constraints, under the co
