I want to output the results of the matlab function 'why' in GUI. But i am unable to do so.. I can output numbers or specific text but i cannot output a result of another function when the answer is in the form of a string.

%i
function pushbutton4_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton4 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
a1 = why;
set(handles.text1,'String',a1)

I want to output the results of 'why' in a static text box called 'text1' when i push a push button called 'pushbutton4'.

Thank you for your help.

The built in why function does not contain outputs. you can make a modified why called mywhy(n) which all you really need to modify is to change the top line to

 function a = mywhy(n)

and maybe if you do not want to have it display in the command window, comment out line 21 where it says disp(a);
