摘要
最小二乘法直线似合是处理实验数据常用的方法 ,由于其计算繁琐 ,一般使用计算机进行拟合。Origin是一种功能强大的数据分析和绘图软件 ,用Origin作直线拟合 ,不用编程 ,简单操作即可获得结果。本文结合实例介绍用Origin软件作直线拟合的方法。
Linear fitting by least squares is a frequently used method of processing experimental data, usually a computer is used due to complex computing process. Origin is powerful software for data analysis and plotting, linear fitting by using it does not program, the results can be got by a simple operation. In this paper the Origin software based on the method of linear fitting is introduced by giving an example.
