max_elem_ifdefined
Ordering functions maximum element ifdefined
- max_elem_ifdefined(a, b, .. , n)
max_elem_ifdefined(a, b, .. , n) is a variant of the max_elem function resulting in defined values if any value of the arguments for an entry in the domain unit is defined. If all arguments contains null values, the resulting value for that entry will be become null.
