- %QR Orthogonal-triangular decomposition.
- % [Q,R] = QR(X) produces an upper triangular matrix R of
- % the same dimension as X and a unitary matrix Q so that
- % X = Q*R.
- % [Q,R,E] = QR(X) produces a permutation matrix E , an
- % upper triangular R with decreasing diagonal elements and
- % a unitary Q so that X*E = Q*R.
- % By itself, QR(X) returns the output of LINPACK'S ZQRDC
- % routine. TRIU(QR(X)) is R.
