D.4.7.7 radical
...............
Procedure from library primdec.lib (see primdec_lib).

Usage:
radical(i); i ideal.

Return:
ideal, the radical of i.

Note:
A combination of the algorithms of Krick/Logar and Kemper is used.
Works also in positive characteristic (Kempers algorithm).

Example:
LIB "primdec.lib";
ring  r = 0,(x,y,z),dp;
poly  p = z2+1;
poly  q = z3+2;
ideal i = p*q^2,y-z2;
ideal pr= radical(i);
pr;
==> pr[1]=z2-y
==> pr[2]=y2z+yz+2y+2
