well...
what else can CSSMers say other than: the error message is crystal clear...

Well, I may sound strange but I'm still wondering how can I solve this problem. Do I have to create a field? And how do I have to do? All the variables are actually defined, so what's needed more?

No, mecc.xa is NOT defined, according to the error message. Set a
breakpoint there, and examine mecc and you will see that it does not
have a "xa" member.

Yeah, I finally got it. At least just the first part. Now the gear is plotted, the slider too. But another problem came out. when moving the slider, I get this:

??? Reference to non-existent field 'edit3'.

Error in ==> guimem>slider1_Callback at 108
set(handles.edit3,'String',num2str(z2))

Error in ==> gui_mainfcn at 96
feval(varargin{:});

Error in ==> guimem at 42
gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating uicontrol Callback



Uh, the part of the GUI for the slider is:




function slider1_Callback(hObject, eventdata, handles)
% hObject handle to slider1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

% Hints: get(hObject,'Value') returns position of slider
% get(hObject,'Min') and get(hObject,'Max') to determine range of slider

z2=get(hObject,'Value');

set(handles.edit3,'String',num2str(z2))
%(mecc.z2-62)/((80-62)/0.5);

% aggiorna la structure
handles.mecc.z2=z2;

handles=diadi(handles);
% calcolo diadi
handles=punti(handles,0); % ottenimento punti
cla
grid on
cilindro(handles); % disegno membri
sfere(handles);
% plot
%axes(handles.axes1)
mecc=dati;
handles.mecc=mecc;

% salva i cambiamenti di handles
guidata(hObject, handles);

Well obviously you do not have a edit box with the tag "edit3".
