Hello!
i display my results in an edit text
set(handles.edit11, 'String', X);
However because the results are too many i cant see the latest results,unless i manually scroll down. any idea how to see the latest results while the are displayed?

Can you not just show results in reverse order so that the latest are always at the top rather than the earliest?

nice thought Adam!it actually works!
however, by reversing the X and displaying it, that means time passing,and in my situation i miss some packets that i receive from a device. i want to display the results at real time.

An example that contains what you wanted (to automatically set the caret position to the end of the editbox) is provided here: http://undocumentedmatlab.com/blog/rich-matlab-editbox-contents#EditorKit

thank you for your answer Yair, but i haven't figured it out yet.
I have an edit text in which i have set the Max value: 2.0
and i use this code
function edit11_Callback(hObject, eventdata, handles)
% hObject handle to edit11 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Hints: get(hObject,'String') returns contents of edit11 as text
% str2double(get(hObject,'String')) returns contents of edit11 as a double
jScrollPane = findjobj(edit11);
jViewPort = jScrollPane.getViewport;
jEdit11= jViewPort.getComponent(0);
endPosition = jEdit11.getDocument.getLength;
jEdit11.setCaretPosition(endPosition);
But this doesn't work.. what should i do?
Thank you very much!

I don't know of any easy way to scroll down to the bottom of an edit text box. How about decreasing the font size? A non-easy way is to use Java robot.
Another way is to delve into Yair's code: http://undocumentedmatlab.com/blog/customizing-listbox-editbox-scrollbars
