# intersect -- compute an intersection

## Description

This function calculates the intersection of a list or sequence of compatible objects.

• intersection -- compute an intersection
• M0nbar -- calculations for divisors and curves on the moduli space of stable n-pointed genus zero curves
• NAGtypes -- Common types used in Numerical Algebraic Geometry
• Polyhedra -- for computations with convex polyhedra, cones, and fans

## Ways to use intersect :

• "intersect(List)"
• "intersect(Sequence)"
• "intersect(Ideal)" -- see intersect(Ideal,Ideal) -- compute an intersection of a sequence of ideals or modules
• intersect(Ideal,Ideal) -- compute an intersection of a sequence of ideals or modules
• "intersect(Module)" -- see intersect(Ideal,Ideal) -- compute an intersection of a sequence of ideals or modules
• "intersect(Module,Module)" -- see intersect(Ideal,Ideal) -- compute an intersection of a sequence of ideals or modules
• intersect(RRi) -- computes intersection of input intervals
• intersect(RRi,RRi) (missing documentation)
