应用MATLAB求解经典物理若干典型问题
The application of MATLAB in solving some classical physics questions
摘要
MATLAB是 MathWorks公司推出的一套科学计算软件,MATLAB的意思是矩阵实验室。MATLAB具有起点低、功能强大、易学易用以及兼有数值运算和符号运算功能的优点。利用MATLAB,绘图十分方便,它既可以绘制各种图形,包括二维图形和三维图形,还可以对图形进行修饰和控制。本文通过在MATLAB环境下编写通过科学计算解决经典物理问题,如力学、热学、电磁学中的一些常见问题。本文的思路主要是,先介绍经典物理习题,然后对习题进行分析,解答,再通过MATLAB软件进行编程,模拟实验结果。通过多次验证。得到所需答案。再通过图形绘制,形象的描绘出图形,与预期结果进行比较、验证。作出总结。本文展示的MATLAB软件在解决物理问题中的应用。

ABSTRACT
.MathWorks MATLAB is introduced in a puting software, MATLAB means Matrix Laboratory . MATLAB has a low starting point, powerful, easy to use, and both numerical calculation and symbolic operation advantages. Using MATLAB, the drawing is very convenient, both to draw various graphics, including the two-dimensional graphics and three-dimensional graphics, graphics can also be modified and controlled. This article written by the MATLAB environment to solve by classical physics puting problems, such as mechanical, thermal, ics mon problems. The main idea of this paper is to introduce classical physics problems, and then exercises to analyze, answer, and then programmed by MATLAB software to simulate the experimental results. Through multiple authentication. Get the answers you need. And through graphics rendering, the image depicts the graphics, compared with the expected results to verify. Conclusion. This article presents the MATLAB software to solve the problem of physics.

引言
近几十年来,计算机技术的广泛应用已经深入地影响到社会的各个方面,大大加快了社会的变革进程,计算机的应用离不开计算语言,而计算语言本身也处于不断的发展之中。
MATLAB是MATrix LABoratory (矩阵实验室)的缩写,它自从1984年由美国MathWorks 公司推出以来,经过不断
