D.16.2.31 minkowskiSum

Syntax:

Polymake::minkowskiSum( polytope p, polytope q )
Polymake::minkowskiSum( polytope p, cone c )
Polymake::minkowskiSum( cone c, polytope q )
Polymake::minkowskiSum( cone c, cone d )

Assume:

same ambient dimension.

Type:

polytope

Purpose:

the Minkowski sum of the two input arguments.

Note:

The Minkowski sum of two cones is just the cone generated by their union.
