Would this work?

f1=figure;
...
status=close(f1);

You can then check the "status" using "if"

thank you because of your answer..yes it works..but I want to start the loop when I close the figure by clicking on the close button!!

a simple example

f1=figure;
set(f1,'DeleteFcn','for k=1:10; disp(k);end')

then close the figure manually
