poly_initial_term

poly_initial_term(F)
: It returns the initial term of a polynomial F with respect to the given weight vector.
poly_initial_term(F | 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

Example:

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