RE: QR and permutation matrix
There is indeed no need to have a permutation matrix, you can check that in giac in vecteur.cc in qr_ortho, the idn matrix is here for compatibility. There is pivoting in the sense that to reduce a given column the line with highest absolute value is choosen. Can you explain what is the reason behind having a permutation matrix?
