A QR factorization is a factorization of a matrix A into a product A = QR of an orthogonal matrix Q and an upper triangular matrix R. This kind of decomposition is useful in solving linear least squares problems and in the eigendecomposition of a matrix, which shows the structure of the matrix in terms of its eigenvalues and eigenvectors.
