| This article is about a function from ApCoCoA-1. |
Num.SingularValues
Computes the singular values of a matrix.
Syntax
Num.SVD(A:MAT):[S:LIST]
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 singular values of the given matrix A.
@param A The matrix we want to analyze.
@return A list containing the singular values of A.
Example
D:=[[1,2,7,18],[2,4,9,12],[23,8,9,10]]; Dec(Num.SingularValues(D),3); -- CoCoAServer: computing Cpu Time = 0 ------------------------------- ["33.091", "17.047", "3.365"] -------------------------------
