实验内容:

function varargout =jisuanqi1(varargin)%JISUANQI1M-file for jisuanqi1.fig %JISUANQI1,by itself,creates a new JISUANQI1or raises the existing %singleton*.%%H =JISUANQI1returns the handle to a new JISUANQI1or the handle to %the existing singleton*.%%JISUANQI1('CALLBACK',hObject,eventData,handles,...)calls the local %function named CALLBACK in JISUANQI1.M with the given input arguments.%%JISUANQI1('Property','Value',...)creates a new JISUANQI1or raises the %existing singleton*.Starting from the left,property value pairs are %applied to the GUI before jisuanqi1_OpeningFunction gets called.An %unrecognized property name or invalid value makes property application %stop.All inputs are passed to jisuanqi1_OpeningFcn via varargin.%%*See GUI Options on GUIDE's Tools menu.Choose "GUI allows only one %instance to run (singleton)".%%See also:GUIDE,GUIDATA,GUIHANDLES

%Edit the above text to modify the response to help jisuanqi1

实验结果及分析：

实验心得：

这次实验做的是电脑附件里的计算器，通过该实验我更熟悉掌握了MATLAB中GUI各控件使用方法及应用，最后并利用GUI设计出了计算器，这些让我对GUI页面中的各控件的功能有了进一步的了解。
