I have a GUI(has a uitextarea) which takes few inputs and can initiate a program's run.. The GUI has a uitextarea in it.
In the program a certain string will be printed multiple times.
I have tried the following to show the output to the uitextarea
for 1:100
app.OutputTextArea_2.Value = textToDiplay + i;
It is working..But it replaces the earlier values.
May I know how I can keep appending the current text to the already existing text uitextarea.
Thanks.

Thanks for the answer. But I have solved the problem in a different way.
text =""
for i:100
text = text + i %%something like this..
text = sprintf('%s \n %s',text,textToDiplay);
app.OutputTextArea_2.Value = text;
This things works like a charm.

frank - try concatenating the existing data with the new
for k = 1:100
app.OutputTextArea_2.Value = [app.OutputTextArea_2.Value "," num2str(textToDiplay + k)];
end
It's unclear what your i and textToDiplay are strings or numbers. I've assumed the latter, so have used num2str to do the conversion.
