borderbasis.BorderBasis

Compute BB of an ideal w.r.t. to an order ideal

Syntax

$borderbasis.BorderBasis(F:LIST,OO:LIST):LIST

Description

Computes the border basis of the ideal <formula>I=<F&gt</formula>; with respect to the order ideal OO. Gives an error messages if no border basis exists. Uses the O_sigma(I) border basis and the BB transformation. The input is a list of poly F and a list of terms OO. The output is a list of poly.
