Num.ProjectAVI
Computes the least squares solution of the general problem Ax=b, where x are coefficients of an order ideal.
Syntax
Num.ProjectAVI(Mat:MAT, Vec:MAT, OI:LIST):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.
This command computes the least squares solution of the general problem Ax=b, if there is no exact solution. The solution x has to be interpreted as the coefficients of the terms in the order ideal.
@param Mat Matrix A
@param Vec Vector B as a matrix.
@param OI Order Ideal
@return The least squares solution of Ax=b interpreted as coefficients of OI.
Example
Dec(Num.ProjectAVI([[1,1],[0,1],[1,1]],[[0],[1],[0]],[x,y]),2); -- CoCoAServer: computing Cpu Time = 0 ------------------------------- [<quotes>-0.99 x +1 y </quotes>] -------------------------------
