1.可进行加减乘除四则运算

2.可进行清零,退出等

三、界面设计及运行结果❽OO Calculator.fig.or OOCalculatorexit-Calculator93Calculatorexh5*8exitr-Calculator401-3简单的实例测试O

五、心得及体会通过这次matlab课程设计，让我对mat lab有了更深的了解.Ma tlab不仅给我们更方便的编程体验,其中强大的数值运算，信号处理等功能更是我们专业实现相关系统设计的好工具00000

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gu i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mat lab中的gu ide生成了简单的计算器程序
