 Usage:  {Q,R} = qrmat(y,aux)   

 

 Input:



  y                      n x p matrix. y must be the output of qr(...). 

                         

                         

  aux                    p x 1 vector. aux must be the output of qr(...). 

                         

                         

 Output:



  Q                      n x p matrix. Q is an orthogonal matrix of the QR
