How can I update the results from a Timer to a text box every 5 second?

My codes are shown as below:

TimeSpan = str2double(get(handles.edit1,'String'));
Parameter = str2double(get(handles.edit2,'String'));

My function is

funcion Output=MyFuc(Parameter)
  Output=sin(Parameter);
end

How can I show 'Output' in textbox ('edit3') every 5 seconds (let's say TimeSpan=5);

So many thanks. I've been working on this for 2 days. Still cannot find correct answer....

Many thanks to everyone helping me.

h = uicontrol('Units','Normalized','FontSize',15,'Position',[0.1 0.1 0.8 0.8],...
            'Style','Text');
drawnow;
T = timer('Period',5,'StartDelay',0,'TimerFcn',@(src,evt)set(h,'String',evalc('why')),...
        'ExecutionMode','FixedRate');
start(T)

thanks, But is it possible to share me any codes based on my question?

What's missing from what Sean gave? Your timer callback function will have to be something like this:

@(~,~) set(handles.edit3,'String',num2str(MyFuc(str2double(get(handles.edit2,'String')))))

Each time this is called, it reads the value in edit2, passes that to your function, and sets the value in edit3 to be the result.

it works now. Thank you very much... :-)
