Function Crossjoin

Returns the cross product of one or more sets.

The Crossjoin function returns the cross product of two or more specified sets. The order of tuples in the resulting set depends on the order of the sets to be joined and the order of their members. For example, when the first set consists of {x1, x2,...,xn}, and the second set consists of {y1, y2, ..., yn}, the cross product of these sets is:

{(x1, y1), (x1, y2),...,(x1, yn), (x2, y1), (x2, y2),...,
(x2, yn),..., (xn, y1), (xn, y2),..., (xn, yn)}
