Incomplete givens orthogonalization based on Bi-down dating
N. A., Atinah; F. Z., Okwonu (Universiti Malaysia Perlis (UniMAP)Institut Matematik Kejuruteraan, 2010-06-02)In this paper we present incomplete Givens orthogonalization technique(IGOT) based on bi-down dating techniques which zero-out entries based on the structure of interest(upper or lower triangular),the incomplete Cholesky ... -
QR decomposition via givens rotations
F. Z., Okwonu; Noor Atinah, Ahmad (Universiti Malaysia Perlis (UniMAP)Institut Matematik Kejuruteraan, 2010-06-02)Different forms of Givens rotations have been proposed and available in the publishing industry. In this paper we derive via Pythagoras and Taylor series expansion to establish a noble ideal on the derivation of Givens ...
