ToricInvariants -- Given a projective toric variety, the package computes the degree and codimension of the dual, the Euclidean distance degree, polar degrees, and Chern-Mather class

Given a projective toric variety X_A defined by a full rank integer matrix A with the vector (1,1,...,1) in its row space, the package computes the degree and codimension of the dual (i.e. the A-discriminant variety), the Euclidean distance degree of X_A, the polar degrees of X_A, and the Chern-Mather class of X_A. Note that we do not require that X_A is normal. This package uses the algorithms described in [1] and [2]. For definitions of the objects computed by the package see [1,2].
