HIntersection

intersection of ideals
Syntax 

HIntersection(I_1:IDEAL,...,I_n:IDEAL):IDEAL
HIntersectionList(L:LIST of IDEAL):IDEAL

Description
The function HIntersection returns the intersection of I_1,...,I_n using a Hilbert-driven algorithm. It differs from Intersection only when the input is non-homogeneous, in which case, HIntersection may be faster.

The coefficient ring must be a field.

Example 
  Use R ::= QQ[x,y,z];
  HIntersection(Ideal(x-z,y-2z), Ideal(x-2z,y-z));
Ideal(x + y - 3z, y^2 - 3yz + 2z^2)
