1、引言 I 摘要 MATLAB 是目前世界上最流行的、应用最广泛的工程计算和仿真软件，它将计算、可视化和编程等功能同时集中于一个易于开发的环境。 MATLAB 主要应用于数学计算、系统建模与仿真、数学分析与可视化、科学与工程绘图和 用户界面设计等。 MATLAB 是 Matrix Laboratory 的缩写，是由 MathWorks 公司于 1984 年推出的一个交互式开发系统，其基本数据要素是矩阵。 MATLAB 的语法规则简单，适用于专业科技人员的思维方式和书写习惯；而且 MATLAB 可适用于多种平台，随着计算机软、硬件的更新而及时升级 ，使得编程和调试效率大大提高。 目前， MATLA
2、B 已经成为应用代数、自动控制理论、数理统计、数字信号处理、动态系统仿真和金融等专业的基本数学工具，各国的高等学校纷纷将MATLAB 正式列入本科生和研究生课程的数学计划中，成为学生必须掌握的基本软件之一 。 本文首先对 MATLAB 的功能进行简单介绍，再利用一些常用信号作为实验对象，对其时域运算与变换进行猜想和理论分析，再使用 MATLAB 的各功能对猜想和分析进行验证，同时将这些常用信号的波形用 MATLAB 的制图功能绘制出来，即利用 MATLAB 进行对常用信号的可视化。 关键词 ： MATLAB、常用信号、时域运算与变化、可视化 电子科技大学成都学院专科毕业设计论文 II Abst
