Hi, That code is exactly what I'm looking for, thanks!! However when I type $a=new Set<Set<Vector>>; foreach $e (@{$c->GRAPH->EDGES}) { $a+=new Set<Vector>(map ($c->VERTICES->[$_],@{$e})); } I get the following ERROR message: ERROR: reference to an undeclared variable $e at input line 1.

Hello, Hopefully there's someone out there who can help me with this. I want to be able to answer the following question: "F is a set of vectors in the semigroup N^d (d copies of the the non-negative integers). Define P = conv(F) i.e. the convex hull of F. Given u_1 and u_2 in F, is [u_1, u_2] an ed...
