This operator creates and returns a function equal to the difference between the functions f1 and f2. The argument functions f1 and f2 must be defined on the same interval. The resulting function is defined on the same interval as the arguments. See also: IloNumToAnySetStepFunction.

This operator creates and returns an interval list equal to the difference between the interval list intervals1 and the interval list intervals2. The arguments intervals1 and intervals2 must be defined on the same interval. The resulting interval list is defined on the same interval as the arguments. See also IloIntervalList.
