Num.IsAppBB

Checks if a given set of polynomials is an approximate border basis.
Syntax
          
Num.IsAppBB(Polys:LIST, OI:LIST, Epsilon:RAT):RAT

          

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.

This command checks if a set of polynomials is an approximate border basis with respect to an order ideal and a threshold number Epsilon.

Example
Use P::=QQ[x,y];
Res := Num.AVI([[1,1],[0,1]],0);
Num.IsAppBB(Res[1],Res[2],0.1);
