But it didn't work properly.what to do?
% --- Executes on button press in Plott.
function Plott_Callback(hObject, eventdata, handles)
% hObject handle to Plott (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
strr=get(handles.screen,'string');
syms x y;
axes(handles.axes1);
x=0:0.1:10;
y=str2sym(strr);
fplot(y,[-10 20]);
guidata(hObject,handles);
