Class Jampack.Zqrd

java.lang.Object
   |
   +----Jampack.Zqrd

public class Zqrd
extends Object
Implements a QR decomposition. Specifically, given a matrix A there are is a unitary matrix Q such that
    QHA = R
where 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.


Variable Index

 o Q
The unitary matrix Q
 o R
The R factor.

Constructor Index

 o Zqrd(Zmat)
Constructs a Zqrd from a Zmat.

Variables

 o Q
 public Zmat Q
The unitary matrix Q

 o R
 public Zutmat R
The R factor. If A.nr>A.nc then R is square of order A.nc. Otherwise R has the same dimensions as A.

Constructors

 o Zqrd
 public Zqrd(Zmat A) throws JampackException
Constructs a Zqrd from a Zmat.

Parameters:
A - A Zmat
Returns:
The Zqrd of A
Throws: JampackException
