ApCoCoA-1:Num.ProjectAVI

Numerical.ProjectAVI

Calculates the least squares solution to the general problem Ax=b, where x are coefficients of an order ideal

Syntax

Num.ProjectAVI(Mat:Matrix, Vec:Matrix, OI:PolyList):Poly;

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.

Calculates the least squares solution to the general problem Ax=b, when there is no exact solution. The solution x is interpreted as the coefficients of the terms in the order ideal.

Example

Dec(Num.ProjectAVI([[1,1],[0,1],[1,1]],[[0],[1],[0]],[x,y]),2);
