Specifying questdlg position

‘MFquestdlg’ is just a simple modification of ‘questdlg’ which enables you to specify the position of questdlg on the screen.
Everything is like the original ‘questdlg’, except that you need to determine your desirable position of the dialog box.
Specify the position with a two-element vector of the form:
[left, bottom]
where ‘left’ and ‘bottom’ define the distance from the lower-left corner of the screen to the lower-left corner of the question dialog box. ‘left’ and ‘bottom’ are NORMALIZED units, obviously between 0 and 1. The position vector must be added as the first element of ‘MFquestdlg’. An example could be:
button = MFquestdlg ( [ 0.6 , 0.1 ] , 'Is the position proper?' , 'Is it OK?' );
