Abstract
This letter presents a new fast QR algorithm based on Givens rotations using a priori errors, The principles behind the triangularization of the weighted input data matrix via QR decomposition and the type of e rrors used in the updating process are exploited in order to investiga te the relationships among different fast algorithms of the QR family, These algorithms are classified according to a general framework and a detailed description of the new algorithm is presented.
