definition

argmax_ifdefined(a, b, .. , n) is a variant of the argmax function resulting in defined values if any value of the arguments for an entry in the domain unit is defined. If all arguments contain null values, the resulting value for that entry will be null. If all arguments contain the same value, e.g. A=0, B=0, C=0, then the result will be the first argument.
