# exteriorPower(ZZ,ToricVectorBundle) -- the 'l'-th exterior power of a toric vector bundle

## Description

exteriorPower computes the l-th exterior power of a toric vector bundle in each description. The resulting bundle will be given in the same description as the original bundle. l must be strictly positive and at most equal the rank of the bundle.
