Re: Rank of an elliptic curve

? ?ellanalyticrank
ellanalyticrank(e, {eps}): returns the order of vanishing at s=1 of the
L-function of the elliptic curve e and the value of the first non-zero
derivative. To determine this order, it is assumed that any value less than eps
is zero. If no value of eps is given, a value of half the current precision is

For older version of GP, there is a script at
