call callback function in my code

  function SaveDataButtonPushed(app, event)
              list=app.portFolio_struct.List(:,1); 
          [eq,sis,RifSis]=MPV_SERAFINI_Load_PortfolioManage(app,list);
          [MPV_Portfolio_readSaved.Eq]=eq;
          [MPV_Portfolio_readSaved.Sis]=sis;
          [MPV_Portfolio_readSaved.RifSis]=RifSis; 
          [MPV_Portfolio_readSaved.dateSavePtf]=datetime('today','Format','dd/MM/yyyy');  
           save('MPV_Portfolio_readSaved.mat','-struct','MPV_Portfolio_readSaved'); 
           app.MPV_Portfolio_readSaved=MPV_Portfolio_readSaved; %%lo metto nelle proprieta perche  lo carico all'inizio allo scopo di visualizzare il campo  [MPV_Portfolio_readSaved.dateSavePtf]
        end

hi, if i press this button (see pics) it call SaveDataButtonPushed(app, event) and it's ok

but if in my code i call it

if app.ReadSaveDATACheckBox.Value %% se sono qua e ReadSaveDATACheckBox e' =1 vuol dire che

app.SaveDataButtonPushed(app)

end

i get this error

annot access method 'SaveDataButtonPushed' in class 'MPV_PortFolio'.

How can i call this function in my code?

You will need to set the Access attribute of the method definition to permit your code to call the method. https://www.mathworks.com/help/matlab/matlab_oop/method-attributes.html
