Orthogonal-triangular decomposition - MATLAB qr
Description [Q,R] = qr(A), where A is m-by-n, produces an m-by-n upper triangular matrix R and an m-by-m unitary matrix Q so that A = Q*R. [Q,R] = qr(A,0) produces the economy-size decomposition. If m > n, only the first n columns of Q and the first n row...
