I have a GUI named g1,g1 consists of a edit text and a pushbutton;
In the pushbutton_callback(),it invokes function M1(a1,a2);
When invokes M1(a1,a2),some strings,such 'Step1 finished','Step2 finished' and so on,are produced.
I hope these strings can be shown in the Edit Text in turn,such as
Step1 finished
Step2 finished
Step3 finished
Thank you very much!

I think the max property of an edit text box has to be 2 to get multiline text. Then you need to pass handles to M1, in addition to a1 and a2. Then in M1 you do this
info = sprintf('Step 1 finished.\nStep 2 finished.\nStep 3 finished.');
set(handles,editText1, 'String', info);
You can do that to a static text without changing the max property.

Alternately, set the max property to 2 (or larger) and
set(handles.editText1, 'String', {'Step 1 finished.', 'Step 2 finished.', 'Step 3 finished.'})
To do this incrementally,
set(handles.editText1, 'String', {});
for K = 1 : 3
S = get(handles.editText1, 'String');
S{end+1} = sprintf('Step %d finished.', K);
set(handles.editText1, 'String', S);
drawnow();
end
