Num.IsAVI

Checks if a given set of polynomials vanishes at a given set of points.
Syntax
          
Num.IsAVI(Polys:LIST, Points:MAT, Epsilon:RAT):[A:INT or RAT,B:INT or 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 vanishes at a set of points Epsilon approximately. The polynomials are preprocessed first to have norm 1.

Example
Use P::=Q[x,y,z];
Num.IsAVI([x+1,x^2],[[0]],0.1);
