Matlab语言在物理实验数据处理中的应用

The Application of Matlab Language in Data Processing of Physical Experiment

以单摆测量重力加速度实验的数据处理为例,探讨了用Matlab语言对物理实验数据进行最小二乘法的处理。与传统的实验数据处理方法相比,用Matlab处理物理实验数据准确快捷,能有效避免手工处理带来的误差,Matlab的可视化功能也可以更加直观地反映实验结果,适合在实验教学中应用。

The paper introduces the least square method to the data of Matlab language through taking the examples of gravity acceleration with the single pendulum.In comparison with the traditional methods,the present program can avoid the man-made errors effectively.The experiment result can be reflected intuitively with the visual function of the Matlab.This method is correct and fast and fit for the experiment teaching.
