Given r Cartier divisors D1,...,Dr on a toric variety X we have a locally free sheaf
OO_X(D1)+...+OO_X(Dr)
of rank r. Cox, Little, and Schenck outline an algorithm for constructing the fan of the corresponding vector bundle on page 337 of their book Toric Varieties. Is this algorithm a feature of sage? If not, has anyone written it down in sage?
