How to resolve empty inputdlg box issue?

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))
