[MATLAB] Non riconosce delle variabili

[franksisca]

ragazzi, questo è il codice:

function varargout = fig1(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @fig1_OpeningFcn, ...
                   'gui_OutputFcn',  @fig1_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end
---------------------------------------------------------------------------------------------
function fig1_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
if strcmp(get(hObject,'Visible'),'off')
    plot(rand(5));
end
---------------------------------------------------------------------------------------------
function varargout = fig1_OutputFcn(hObject, eventdata, handles)
varargout{1} = handles.output;
function pushbutton1_Callback(hObject, eventdata, handles)
axes(handles.axes1);
cla;

popup_sel_index = get(handles.popupmenu1, 'Value');
switch popup_sel_index
    case 1
        plot(rand(5));
    case 2
        plot(sin(1:0.01:25.99));

function OpenMenuItem_Callback(hObject, eventdata, handles)
file = uigetfile('*.fig');
if ~isequal(file, 0)
    open(file);

delete(handles.figure1)

load 'dati.txt';

plot(T,YOSS,'*')
---------------------------------------------------------------------------------------------
function B0Text_Callback(hObject, eventdata, handles)
 Bzero = str2double(get(hObject,'string'));
  if isnan(Bzero)
    errordlg('Inserire valore numerico!!!','Valore Errato.','modal')
 end
if ispc
    set(hObject,'BackgroundColor','white');

 if isnan(Kc)

 end
---------------------------------------------------------------------------------------------
function KCText_CreateFcn(hObject, eventdata, handles)
if ispc
    set(hObject,'BackgroundColor','white');
else
    set(hObject,'BackgroundColor',get(0,'defaultUicontrolBackgroundColor'));

end
---------------------------------------------------------------------------------------------
function Indici_Callback(hObject, eventdata, handles)
n_indice= get(hObject,'Value');
switch n_indice
    case 2
        n_indice=1;
    case 3
        n_indice=2;
    case 4
        n_indice=77;
    otherwise 
        n_indice=-1;
end
---------------------------------------------------------------------------------------------

    set(hObject,'BackgroundColor',get(0,'defaultUicontrolBackgroundColor'));
end
---------------------------------------------------------------------------------------------
function loadStartParametre_Callback(hObject, eventdata, handles)
par_iniziali=[Bzero, Kb, Kc]

in loadStartParametre_Callback(l'ultimo metodo), quando popolo par_iniziali non mi riconosce Bzero, qualcuno saprebbe dirmi il perchè????


Grazie a tutti.

risolto, praticamente si deve dichiarare la variabile global solo quando serve.


Ciao a tutti e grazie uguale
