MATLAB GUI实现简单的计算器

欢迎大家来到IT世界,在知识的湖畔探索吧!

利用MATLAB的GUI界面设计一个简单的科学计算器，界面如图;

具体功能：四则运算、三角函数计算、对数和指数运算、求多项式方程计算、括号、关闭、清除、后退一步等基本计算功能。下面呈现主要程序，完整程序，需要的可以打赏10元及以上，进行联系，或者发截图到微信公众号云龙派对话窗口或者直接在公众号里，点击“联系掌门”按键，即可获得源程序，编程不易，还请见谅。

数字按键部分程序

function pushbutton1_Callback(hObject, eventdata, handles)
% 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)
textString = get(handles.edit1,'String');
textString = strcat(textString,'1');
set(handles.edit1,'String',textString);
guidata(hObject, handles);

退一步back按键程序

欢迎大家来到IT世界,在知识的湖畔探索吧!function pushbutton13_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton13 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
textString=get(handles.edit1,'String');
as=char(textString);
n=length(textString);
textString=as(1:n-1);
set(handles.edit1,'String',textString)
guidata(hObject, handles);

清除按键程序

function pushbutton14_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton14 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
textString = get(handles.edit1,'String');
textString = get(handles.edit2,'String');
set(handles.edit1,'String','');
set(handles.edit2,'String','');
guidata(hObject, handles);

运算符部分程序

欢迎大家来到IT世界,在知识的湖畔探索吧!% --- Executes on button press in pushbutton17.
function pushbutton17_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton17 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
textString = get(handles.edit1,'String');
textString = strcat(textString,'*');
set(handles.edit1,'String',textString);
guidata(hObject, handles);
