1、matlab课程设计报告题 目简易计算器的设计学 院电子信息工程学院专 业电子信息学生姓名和学号指导教师一 、选题目的及意义 GUI的广泛应用是当今计算机发展的重大成就之一，它极大地方便了非专业用户的使用。人们从此不再需要死记硬背大量的命令，取而代之的是可以通过窗口、菜单、按键等方式来方便地进行操作，而在matlab有很简单的gui设计工具，我们可以通过这个工具轻松地构建我们想要的程序，从而实现与用户的信息交互。本次课程设计是使用了matlab中的guide生成了简单的计算器程序。 二、源代码function varargout = Calculator(varargin) %Simple C
