Abstract

Luk and Qiao introduced an algorithm for the generalized ULV decomposition (ULLVD). The proposed decomposition scheme performs the rank-revealing operation, but requires a lower computational cost in the updating of new data as compared to the generalized singular value decomposition (GSVD). In this paper, we extend their algorithm for handling downdating, and propose a systolic array structure for implementing both updating and downdating. A scheme for rank revealing is also implemented on the proposed systolic array.
