# intersection -- compute an intersection

## Description

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

• 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

• "intersection(Polyhedron,Cone)" -- see intersection -- computes the intersection of cones, and polyhedra
• "intersection(Polyhedron,Polyhedron)" -- see intersection -- computes the intersection of cones, and polyhedra
• intersection(Matrix) -- Deprecated variant of {\tt coneFromHData}
• intersection(Matrix,Matrix) -- Deprecated variants of {\tt polyhedronFromHData} and {\tt coneFromHData}
• "intersection(Matrix,Matrix,Matrix,Matrix)" -- see intersection(Matrix,Matrix) -- Deprecated variants of {\tt polyhedronFromHData} and {\tt coneFromHData}
• intersection(RRi,RRi) -- computes intersection of input intervals
