BBasis

border basis of a zero dimensional ideal

Syntax

BBasis(I:IDEAL):LIST

Description

The function BBasis calls the ApCoCoAServer to compute the border basis of a zero dimensional ideal I. The input is a zero-dimensional ideal I. The output is a list of polynomials.

Example

Use Q[x, y], DegLex;
I := Ideal([x^2, xy + y^2]);
BB := BBasis5(I);
-- CoCoAServer: computing Cpu Time = 0
-------------------------------
BB;
[xy + y^2, x^2, y^3, xy^2]
-------------------------------
