D.4.3.2 zeroR

Procedure from library assprime.lib (see assprime_lib).

Usage:
zeroR(I,[n]); I ideal, optional: n number of processors (for parallel computing)

Assume:
I is zero-dimensional in Q[variables]

Return:
the radical of I

Example:
 
LIB "assprime.lib";
ring R = 0, (x,y), dp;
ideal I = xy4-2xy2+x, x2-x, y4-2y2+1;
zeroR(I);
==> _[1]=y2-1
==> _[2]=x2-x
