QR Decomposition AlgorithmspectroscopyAn accurate and stable algorithm, QR Decomposition Algorithm (QRDA) is initially presented into the chemistry field. The basic principle of QR Multivariate Calibration Algorithm (QRMCA) is investigated, and the complexes system of sodium tripolyphosphate (STPP), sodium...
Compared to 3n m 2 time steps for the Givens QR Decomposition it is uneconomic. In this paper we have used some recent results for the elimination of the computational and data broadcast, and data synchronization to derive a fully localized form of the Householder QR Decomposition algorithm. We...
Another important field where QR decomposition is often used is in calculating the eigenvalues and eigenvectors of a matrix. This method is known as the QR algorithm or QR iteration. Now we'll see how the QR factorization procedure can facilitate the task of solving a system of linear ...
