Numerical.IsAVI
Checks if a given set of polynomials vanishes at a given set of points
Syntax
Num.IsAVI(Polys:PolyList, Points:Matrix, Epsilon:Number):[A:Number,B: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 vanishes at a set of points epsilon approximately. The polynomials are preprocessed first to have norm 1.
The function returns a number A which specifies how well the points vanish on average and the number B contains the maximal evaluation value.
Example
Num.IsAVI([x[1]+1,x[1]^2],[[0]],0.1); -- CoCoAServer: computing Cpu Time = 0 ------------------------------- [1/2, 1] -------------------------------
