Modified givens rotations for inverse updating in qr decomposition verizon dating website

We first discuss basic principles of parallel processing, describing the costs of basic operations on parallel machines, including general principles for constructing efficient algorithms.We illust ..." We survey general techniques and open problems in numerical linear algebra on parallel architectures.

In this paper, this updating algorithm is mapped onto a systolic array with O(n 2 ) parallelism for O(n 2 ) complexity, resulting in an O(n 0 ) throughput.

A long, but by no means complete, bibliography is given. Introduction Turing [365] demonstrated that, in principle, a single general purpose sequential machine could be designed which would be capable of efficiently performing any computation which could be performed by a special purpose sequential machine.

The importance of this universality result for subsequent practical developments in computing cannot be overstated.

For a given matrix H which has d singular values larger than e, we find all rank d approximants H such that "...

In an earlier paper, an approximate SVD updating scheme has been derived as an interlacing of a QR updating on the one hand and a Jacobi-type SVD procedure on the other hand, possibly supplemented with a certain re-orthogonalization scheme.
