jisuanqi.m

用MATLAB实现的计算器 用的是GUI制作的

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