How to show array text into textbox GUI

i have build simple application to recognize image with text. I have problem about to show the label into one textbox. This is my code

for k=1:6

subplot(1,10,k);

subImages{k} = imcrop(b,stat2(k).BoundingBox);

output{k} = 'Ha U+A9B2';

End

set(handles.text2,'string',output);
