The setintersection function takes multiple sets and produces a single set containing only the elements that all of the given sets have in common. In other words, it computes the intersection of the sets.

setintersection(sets...)

Examples

> setintersection(["a", "b"], ["b", "c"], ["b", "d"])
[
  "b",
]

The given arguments are converted to sets, so the result is also a set and the ordering of the given elements is not preserved.

  • contains tests whether a given list or set contains a given element value.
  • setproduct computes the Cartesian product of multiple sets.
  • setsubtract computes the relative complement of two sets
  • setunion computes the union of multiple sets.
