dfield8.m has a few problems:
Error using figure
There is no numb property on the Figure class.
There are several references to 'numb' which fail. When all 'numb' references are changed to 'numbertitle', they succeed.
Conversion to logical from matlab.ui.control.UIControl is not possible.
Error in dfield8 (line 1541)
if notice, if dud.notice
if notice > 0, if dud.notice > 0
allows the program to continue, even though this is clearly not correct code.
