ApCoCoA-1:Num.IsAppBB

Numerical.IsAppBB

Checks if a given set of polynomials is an approximate border basis.

Syntax

Num.IsAppBB(Polys:PolyList, OI:PolyList, Epsilon:Number):A:Number;

Description

Please note: The function(s) explained on this page is/are using the ApCoCoAServer. You will have to start the ApCoCoAServer in order to use

it/them. Please also note that you will have to use an ApCoCoAServer with enabled BLAS/LAPACK support.

Checks if a set of polynomials is an approximate border basis with respect to an order ideal. The function returns the distance to an exact border basis.

Example

Res := Num.AVI([[1,0],[0,1]],0);
Num.IsAppBB(Res[1],Res[2],0.1);
