%      H = GUILOLOS returns the handle to a new GUILOLOS or the handle to

%
%      GUILOLOS('CALLBACK',hObject,eventData,handles,...) calls the local

%      GUILOLOS('Property','Value',...) creates a new GUILOLOS or raises the

Did you solve your problem? i meet the same error, could you help me ?

Answer 1

[Walter Roberson]

At the moment all we can say is that some error occurred when executing running_Callback. Your code for that is

function running_Callback(hObject, eventdata, handles)
% hObject    handle to running (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
a=readfis('FISlolos');
out=evalfis([handles.style handles.mefa],a);
set(handles.hasilrun,'String',out);

so you could get that error if readfis() was not able to find that file, or if evalfis encounted a problem, or if handles.style or handles.mefa or handles.hasilrun do not exist.

Also, the way you used evalfis() is obsolete. Your fis should be the first parameter, as in

out=evalfis(a, [handles.style handles.mefa]);
