MATLAB code for making simple calculator with GUI

function varargout = gui(varargin) % GUI M-file for gui.fig% GUI, by itself, creates a new GUI or raises the existing% singleton*. % H = GUI returns the handle to a new GUI or the handle to% the existing singleton*. % GUI('CALLBACK',hObject,eventData,handles,...) calls the local% function named CALLBACK in GUI.M with the given input arguments. % GUI('Property','Value',...) creates a new GUI or raises the% existing singleton*. Starting from the left, property value pairs are% applied to the GUI before gui_OpeningFcn gets called. An% unrecognized property name or invalid value makes property application% stop. All inputs are passed to gui_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 gui % Last Modified by GUIDE v2.5 21-Apr-2014 11:36:48 % Begin initialization code - DO NOT EDIT  gui_Singleton = 1;gui_State = struct('gui_Name', mfilename, ...'gui_Singleton', gui_Singleton, ...'gui_OpeningFcn', @gui_OpeningFcn, ...'gui_OutputFcn', @gui_OutputFcn, ...'gui_LayoutFcn', [] , ...'gui_Callback', []);if nargin && ischar(varargin{1})gui_State.gui_Callback = str2func(varargin{1});end if nargout[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});elsegui_mainfcn(gui_State, varargin{:});end % End initialization code - DO NOT EDIT  % --- Executes just before gui is made visible. function gui_OpeningFcn(hObject, eventdata, handles, varargin) % This function has no output args, see OutputFcn.% hObject handle to figure% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA)% varargin command line arguments to gui (see VARARGIN) % Choose default command line output for guihandles.output = hObject; % Update handles structure guidata(hObject, handles);  % UIWAIT makes gui wait for user response (see UIRESUME)% uiwait(handles.figure1);  % --- Outputs from this function are returned to the command line. function varargout = gui_OutputFcn(hObject, eventdata, handles) % varargout cell array for returning output args (see VARARGOUT);% hObject handle to figure% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA) % Get default command line output from handles structure varargout{1} = handles.output;   % --- Executes on button press in pushbutton1. function pushbutton1_Callback(hObject, eventdata, handles)x=get(handles.edit1,'String');x=eval(x);set(handles.edit2,'String',x); % hObject handle to pushbutton1 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA)  % --- Executes on button press in pushbutton2. function pushbutton2_Callback(hObject, eventdata, handles) % hObject handle to pushbutton2 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA) set(handles.edit1,'String',0);set(handles.edit2,'String',0);    function edit1_Callback(hObject, eventdata, handles) % hObject handle to edit1 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA) % Hints: get(hObject,'String') returns contents of edit1 as text% str2double(get(hObject,'String')) returns contents of edit1 as a double  % --- Executes during object creation, after setting all properties. function edit1_CreateFcn(hObject, eventdata, handles) % hObject handle to edit1 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles empty - handles not created until after all CreateFcns called % Hint: edit controls usually have a white background on Windows.% See ISPC and COMPUTER. if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))set(hObject,'BackgroundColor','white');end   function edit2_Callback(hObject, eventdata, handles) % hObject handle to edit2 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA) % Hints: get(hObject,'String') returns contents of edit2 as text% str2double(get(hObject,'String')) returns contents of edit2 as a double  % --- Executes during object creation, after setting all properties. function edit2_CreateFcn(hObject, eventdata, handles) % hObject handle to edit2 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles empty - handles not created until after all CreateFcns called % Hint: edit controls usually have a white background on Windows.% See ISPC and COMPUTER. if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))set(hObject,'BackgroundColor','white');end
