一、欲实现的功能如下图
二、实现步骤
2.1、需要用到Pop-Up Menu和坐标轴控件,修改Pop-Up Menu的value值
value=1,对应sin(x),以此类推。
2.2、进入回调函数
function p1_Callback(hObject, eventdata, handles)
% hObject handle to p1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: contents = cellstr(get(hObject,'String')) returns p1 contents as cell array
% contents{get(hObject,'Value')} returns selected item from p1
var=get(handles.p1,'value');
x=0:0.01:2*pi;
axes(handles.axes1);
switch var
case 1
y=sin(x);
plot(x,y);
case 2
y=cos(x);
plot(x,y);
case 3
y=sin(x)+cos(x);
plot(x,y);
end
