# gaussImage -- computes the image the Gauss map

## Synopsis

• Usage:
gaussImage(A)
• Inputs:
• A, , or a list where the columns are lattice points
• Outputs:
• a list, of monomials giving the torus embedding via the Plücker embedding of the image of the Gauss map of the toric variety X_A

## Description

gaussImage is a function. It computes the image of the Gauss map embedded via the Plücker embedding as described in the paper Gauss Maps of Toric Varieties
