基于最小二乘法的分段直线拟合算法

Piecewise linear fitting algorithm based on least square method

本文通过直线方程的斜率和几何意义给出了又一新的分段技巧,再结合最小二乘法提出了一种分段直线拟合的新方法,又给出相应的算法,最后用实例验证该方法的可行性。

This paper, through the slope of linear equation and the geometric meaning, is gives a new piecewise technique, and combined with least square method presents a new method of piecewise linear fitting, and gives corresponding algorithm, finally an example is used to verify the feasibility of this method.
