Gcd of polynomials in matlab

The following Matlab project contains the source code and Matlab examples used for gcd of polynomials. In the longhand polynomial division given as       P(k) = P(k-2) - P(k-1)*Q(k) The quotient Q(k) and the remainder P(k) are obtained from dividing the dividend P(k-2) by the divisor P(k-1).

Manipulate and solve systems of multivariate polynomial equations by computing the groebner basis in matlab

The following Matlab project contains the source code and Matlab examples used for manipulate and solve systems of multivariate polynomial equations by computing the groebner basis . Example: simplify the system of equations   {x^2+2xy^2=0, xy+2y^3=1} >> groebner({'x^2+2*x*y^2','x*y+2*y^3-1'},'lex',{'x','y'}) returns {'y^3-0.
