java.lang.ObjectJampack.Zqrd
public class Zqrd
Implements a QR decomposition. Specifically, given a matrix A there are is a unitary matrix Q such that
QHA = Rwhere R is zero below its diagonal. In constructing this decomposition, Zqrd represents Q as a Zmat. R is represented by a Zutmat.
At a later stage an economical version of the decomposition will be implemented, in which only A.nc columns of Q are returned.
