How to resolve empty inputdlg box issue?
显示 更早的评论
Hello everyone!
I have a inputdlg box. I want the inputdlg box to cancel the processing if the user pressed OK without giving any input in the inputdlg box. How can I do that?
I know how to cancel the processing if Cancel or the close button is pressed.
Thanks in advance!

Try this:
a = inputdlg('Type a number:')
if isempty(a{:})
disp('a is empty') % Information Only To Demonstrate That The Test Works
return
end
fprintf('a = %f\n', str2double(a))
.
