Try this (assuming GUIDE - replace handles with app if using AppDesigner)

if handles.popup1.Value == 1 && handles.popup2.Value == 1 && handles.popup3.Value == 1 && handles.popup4.Value == 1
    handles.button1.Enable = 'on';
else
    handles.button1.Enable = 'off';
end

MATLAB: How can i access elements of popup menu and use it in Push Button callbacks

Hello Anurag,

You can use either of the following solutions:

Solution.1: As you are assigning the values to the workspace you can read it by using evalin command.

function pushbutton1_Callback(hObject, eventdata, handles)
pop1val=evalin('base','pop1val');
pop2val=evalin('base','pop2val');
c=pop1val*pop2val;
set(handles.edit1,'string',c); % here you don't have to convert as the value already in double.

Solution.2:

assignin('base','pop1val',pop1val) This statement you don't require in your code. As you already setting the value of 'UserData' for popupmenu (set(handles.popupmenu1,'UserData',pop1val);)

This is how your code looks now:

function popupmenu1_Callback(hObject, eventdata, handles)
contents= cellstr(get(hObject,'String'));
popchoice1 = contents(get(hObject,'Value'));
if (strcmp(popchoice1,'choice 1'))
    pop1val=10;
elseif (strcmp(popchoice1,'choice 2'))
    pop1val=20;
elseif(strcmp(popchoice1,'choice 3'))
    pop1val=30;
end
set(handles.popupmenu1,'UserData',pop1val);
function popupmenu2_Callback(hObject, eventdata, handles)
contents= cellstr(get(hObject,'String'));
popchoice2= contents(get(hObject,'Value'));
if (strcmp(popchoice2,'a'))
    pop2val=40;
elseif(strcmp(popchoice2,'b'))
    pop2val=50;
elseif(strcmp(popchoice2,'c'))
    pop2val=60;
end
set(handles.popupmenu2,'UserData',pop2val);
function pushbutton1_Callback(hObject, eventdata, handles)
pop1val=get(handles.popupmenu1,'UserData');
pop2val=get(handles.popupmenu2,'UserData');
c=pop1val*pop2val;
set(handles.edit1,'string',c);

Accept it if its work for you!!

Thanks
