Hi everyone,
I am working with checkbox in GUI and I have found that checkbox remains blank at the initial stage.
I need to know how to set the checkbox ticked so that no need to put a checkmark manually in the checkbox.
Any suggestion will be appreciated.

Set the Value property to 1.
uicontrol('Style','check','Value',1)

Another option could be to use
set(handles.checkbox,'value',1) where 1 for checked and 0 for unchecked.

i think in value the first letter should be capital so it will be set(handles.checkbox,'Value', 0);

@Lokendra: properties are not case sensitive. You don't even need to finish typing it, as long as you have a unique match:
figure(1),clf(1)
h_=plot(rand(1,4));
hold on,plot(rand(1,4))
set(h_,'visi','off')
If you use the object notation you do need to be precise:
figure(1),clf(1)
h_=plot(rand(1,4));
hold on,plot(rand(1,4))
h_.Visible='off';

You can use the following for your GUI
% --- Executes on button press in DataEaseInput.
function YourCheckbox_Callback(hObject, eventdata, handles)
% hObject handle to YourCheckbox (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% --- Executes during object creation, after setting all properties.
function YourCheckbox_CreateFcn(hObject, eventdata, handles)
% hObject handle to YourCheckbox (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles empty - handles not created until after all CreateFcns called
set(hObject,'value',1)

I added the comment becasue it clarifies where
set(hObject,'value',1)
must be used. 'set(hObject,'value',1)' must be used in CreateFcn function and not in Callback function.

Maybe I'm getting too familiar with the way GUIs work, but isn't it obvious it needs to be called when you create the object or start your GUI? If you put it in the callback function, it would happen every time you interact with the checkbox.

app.NameOfCheckbox.Value=true; % (or 1) (in startupFcn function)
