Matlab在大学物理实验数据处理中的应用

The Application of Matlab in Data Processing of College Physical Experiment

在大学物理实验中,实验数据的处理是其中重要的一环。手工计算法或在坐标纸描点作图法处理数据是常用的方法。但其效率低,误差较大。为了提高数据处理的效率与精度,本研究利用Matlab软件对相关实验数据进行处理。本文以拉伸法测量金属丝的杨氏模量为例,采用Matlab语言编写程序进行数据处理与作图。结果显示,计算结果与所得图表均与传统的最小二乘法处理的数据一致。

In college physics experiment,the processing of experimental data is an important part.It is a common method to deal with data by manual calculation or drawing on coordinate paper.But its efficiency is low and its error is large.In order to improve the efficiency and accuracy of data processing,the software Matlab is used to process the relevant experimental data.In this paper,taking the measurement of Young′s modulus of metal wire by tensile method as an example,a program written in MATLAB language is used for data processing and drawing.The results show that the calculated results are consistent with the data processed by the traditional least square method.
