Hello !
I have the following function:
try
h = MyFunction(arg1,arg2);
catch
close(h);
end
Unfortunately it doesn't run because if an error occurs in MyFunction, ouput h isn't in the workspace of the main function. Yet, h is set in MyFunction before the error occurs.
How can I close a window opened by MyFunction, with the handle h, if an error occurs in MyFunction ?
Thank you for your help.

Add a try block to MyFunction!
Well that's the easiest way and it's pretty safe. You could also use assignin if you really just want h.

Open the window first, and pass it as an argument to MyFunction.
