rc_interval<T> intersection(const rc_interval<T>& a, const rc_interval<T>& b);

Set operations given two rectangular complex intervals, $A,B ∈RC$ :

hull(const rc_interval<T>& a, const rc_interval<T>& b): Returns an interval that contains both $A$ and $B$ .
intersection(const rc_interval<T>& a, const rc_interval<T>& b): Returns an interval that is the intersection of $A$ and $B$ .
