Dimension of the affine variety generated by polynomials
MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.
MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.
groebner::dimension(polys) computes the dimension
of the affine variety generated by the polynomials in the set or list
The rules laid down in the introduction to the groebner package concerning the polynomial types and the ordering apply.
The polynomials in the list
polys must all
be of the same type. In particular, do not mix polynomials created
An example from the book of Cox, Little and O'Shea (see below):
groebner::dimension([y^2*z^3, x^5*z^4, x^2*y*z^2])
A list or set of polynomials or polynomial expressions of the same type. The coefficients in these polynomials and polynomial expressions can be arbitrary arithmetical expressions.

The implemented algorithm is described in Cox, Little, O'Shea: "Ideals, Varieties and Algorithms", Springer, 1992, Chapter 9.
First, the Gröbner basis of the given polynomials with
respect to the given monomial ordering is computed using
Gröbner basis is then used to compute the dimension of the affine
variety generated by the polynomials.
