I want to put a warning message box at the click of a close button in a matlab figure.
function closed(hObject, eventdata)
close(gcbf);
warndlg('are you sure you want to close','!! Warning !!')
%clear all;
%close;clear
end
however this warning dialog box appears when the window is closed! Where should I put this messagebox exactly!

Looks like you have your call to warndlg after "close(gcbf)". Try putting it above that.

And use questiondlg() instead of warndlg(), as warndlg() does not give the user any way to chose between closing or not.
