QR-Decomposition QR decomposition, also known as QR factorization, is a method used when converting a matrix into the form A = QR. In the formula, A represents the starting matrix, Q represents an orthogonal matrix, and
R represents an upper triangle matrix. An upper triangle matrix is a special kind of square matrix in which all of the entries below the main diagonal are zero. Often, QR decomposition is used in solving the linear least squares problem.
