Here is polynomial GCD over Z: http://sage.math.washington.edu/home/wbhart/gcd.png I haven't yet tried the subresultant algorithm in that region at the bottom left where it is red since removing the bug from pseudo division. However other red regions have now disappeared due to the asymptotically fast integer GCD. Bill. |
