# gaussFiber -- computes the general fiber of the Gauss map

## Synopsis

• Usage:
gaussFiber(A)
• Inputs:
• A, , or a list where the columns are lattice points
• Outputs:
• a list, of monomials giving the torus embedding of an irreducible component of the general fiber of the Gauss map of the toric variety X_A

## Description

gaussFiber is a function. It computes an irreducible component of the general fiber of the Gauss map as described in the paper Gauss Maps of Toric Varieties
