poly_initial_term

poly_initial_term(I)
: It returns the initial ideal of I with respect to the given weight vector.
poly_initial_term(I | weight=key0,order=key1,v=key2)
: This function allows optional variables weight, order, v

The weight is given by the optional variable weight w. It returns @tex ${\rm in}_w (I)$ @end tex

Example:

 poly_initial_term([x^2+y^2-4,x*y-1]|weight=[100,1],v=[x,y]);
