## 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 := BBasis(I); -- CoCoAServer: computing Cpu Time = 0 ------------------------------- BB; [xy + y^2, x^2, y^3, xy^2] -------------------------------
