Class Jampack.Zsvd 

java.lang.Object
   |
   +----Jampack.Zsvd
public class Zsvd
extends Object
Zsvd implements the singular value decomposion of a Zmat. Specifically if X is an mxn matrix with m>=n there are unitary matrices U and V such that 
     U^H*X*V = | S |
               | 0 |
where S = diag(s1,...,sm) with 
     s1 >= s2 >= ... >= sn >=0.
If m<n the decomposition has the form 
     U^H*X*V = | S  0 |,
where S is diagonal of order m. The diagonals of S are the singular values of A. The columns of U are the left singular vectors of A and the columns of V are the right singular vectors.
