EvalHilbertFn

evaluate the Hilbert function
Syntax 

EvalHilbertFn(H:TAGGED("$hp.Hilbert"), N:INT):INT

Description
This function evaluates the Hilbert function H at N. If H is the Hilbert function of a quotient R/I, then the value returned is the same as that returned by Hilbert(R/I, N) but time is saved since the Hilbert function does not need to be recalculated at each call.

Example 
  Use R ::= QQ[w,x,y,z];
  I := Ideal(z^2-xy,xz^2+w^3);
  H := Hilbert(R/I);
  H;
H(0) = 1
H(1) = 4
H(t) = 6t - 3   for t >= 2
