文档介绍：摘要
据我们所了解的知识,可以把振动理解为一种非常普遍的运动形式。要出现波动就必须先要产生振动,振动可以理解为产生波动的前提。可是波的种类却有很多种,种类多而且它们的本质不同,却各有特殊性,可是它们也存在共性,它们都有一定的传播速度,也都有能量的传播。特别的每一种波,他都有特定的函数,也各具特点,我们学习数理方程时,知道一维,二维波动方程,但是由于数理方程很求解,有没有一种直观的方法可以把函数图像画出来。
Matlab是由美国mathwork公司发布的主要面对科学计算、可视化以及交互式程序设计的高科技计算环境。计算功能、符号运算、特别是数据可视化功能都被它集成了。该软件在应用方面主要被集中在这几个方面上:有数值计算和算法开发还有符号表达式运算和推导,数学建模与仿真和数据分析可视化也是其中之一,最后还有科学与工程绘图,本文主要应用矩阵运算、多项式运算、plot函数将波函数的运算结果可视化。

Abstract
We know that a vibration is a mon form of movement. So the spread of vibration wave form, hereinafter referred to as the wave. The types of wave has a lot of, even though the essence of wave is different, but each has particularity, but there are mon, they all have certain transmission speed and the spread of energy can be reflected, interference is diffraction. Each wave of its function are not all the same, also with various features.
Law is the law by Matlab mathwork by main face of scientific calculation, visualization and interactive program design ofthehigh-puting environment. It puting functions, putation, data visualization function. This software applications mainly concentrated in several aspects: numerical calculation, algorithm development, symbolic expression operation and deducing, mathematical modeling and simulation, data analysis and visualization of science and engineering drawing, this paper mainly application putation, polynomial operations, plot function will wave function of the operation result visualization.
Keywords: Wave function;Matlab;The matrix calculation;Plot function
