MATALB_GUI_设计.doc

摘 要：MATLAB的GUIDE是专门用于图形用户界面(GUI)程序设计的快速开发环境。GUI是使用图像，输入的文字，带图标的屏幕的计算机界面，取而代之许多键盘的功能，让用户可以通过图标和鼠标与他们的电脑进行交互，而不是在命令行中输入文本。本文首先介绍了MATLAB的数据可视化功能的基础——MATLAB绘图函数。接着介绍了MATLAB中数据可视化技术的底层概念——句柄图形对象，它为用户操作图形元素提供了最精细的控制方法。在此基础上详细介绍了MATLAB在图形用户界面方面的强大功能，分别介绍了用户界面菜单对象、用户界面上下文菜单对象和用户界面控制对象，主要从介绍GUIDE入手,给出了利用GUIDE制作图形用户界面的基本方法。紧接着就如何设计和制作用户界面对话框作了一定介绍。最后，以周期方波信号的分解为具体实例，说明MATLAB GUI的应用，此例也在一定程度上显示出了MATLAB GUI的强大功能及其优越性。 关键词：MATLAB绘图 句柄图形 GUI程序 信号分解 MATLAB GUI graphical user interface programming Abstract: MATLABs GUIDE is devoted to graphical user interface (GUI) program designed for rapid development environment. GUI is to use images, text input with a computer screen icon interface, replaced many of the functions of the keyboard, so users can icon and mouse to interact with their computers, rather than enter text in the command line. This paper introduces the MATLAB-based data visualization capabilities - MATLAB graphics functions. Then introduced the MATLAB data visualization technology in the underlying concept - Handle Graphics object graphic elements for the user action provides the most precise control. On this basis, details of the MATLAB graphical user interface in terms of power, introduced the object user interface menu, user interface objects and user interface context menu control objects, mainly from the introduction GUIDE start, given the graphical user interface using GUIDE production the basic method. Finally, the decomposition cycle square wave signal for specific examples to illustrate the MATLAB GUI application, this case also to a certain extent, the MATLAB GUI shows the power and superiority.
