Mathstudio在大学物理实验数据处理中应用

Application of Mathstudio in the Experimental Data Processing of University Physics

将数学软件Mathstudio应用到大学物理实验数据处理中,进行描述性统计、推断统计、求不确定度、线性回归等运算。Mathstudio具备数值运算和符号运算功能,使用数组和切片(Slice)操作,内置大量数学函数,微积分、统计等功能很强大,作图和动画也方便。Mathstudio不用安装、编译,浏览器打开网址即可运行,可逐行调试,命令格式简单。示例结合线性代数理论,使用了雅可比矩阵、海森矩阵、范数、线性回归、作图等命令,实现Mathstudio编程计算空心圆柱体体积的不确定度、铜-康铜热电偶温差电势的线性回归模型,程序简短精练,结构清晰,提高了数据处理效率。Mathstudio编程效率高,难度较低,适合小规模数据快速分析,也能进一步开发更专业的数据处理功能。

Mathematical software Mathstudio is applied to the experimental data processing of university physics to perform operations such as descriptive statistics,inferential statistics,uncertainty and linear regression.Mathstudio has the function of numerical and symbolic operations,uses arrays and slice operations,has a large number of built-in mathematical functions,has powerful functions such as calculus and statistics,and is also convenient for graphing and animating.Mathstudio does not need to be installed and compiled,and it can be run by opening the Web site in the browser and debugged line by line with the simple command format.Combined with the linear algebra theory,the example uses commands such as the Jacobi matrix,Hessian matrix,paradigm,linear regression and graphing to realize the calculation of the uncertainty of the volume of hollow cylinders and the linear regression of copper-constantan thermocouple temperature difference potential by Mathstudio programming,and the program is short and concise with clear structure,which improves the efficiency of data processing.Mathstudio programming is highly efficient and less difficult,and it is suitable for the rapid analysis of small-scale data and also can further develop the more professional functions of data processing.
