Successive band reduction (SBR) is a two-phase approach for reducing a full symmetric matrix to tridiag-onal (or narrow banded) form. In its simplest case, it consists of a full-to-band reduction followed by a band-to-tridiagonal reduction. Its richness in BLAS-3 operations makes it potentially more eecient on high-performance architectures than the(More)
Esprit is an algorithm for determining the xed directions of arrival of a set of narrowband signals at an array of sensors. Unfortunately, its computational burden makes it unsuitable for real time processing of signals with time-varying directions of arrival. In this work we develop a new implementation of esprit that has potential for real time(More)
Grassman, Taksar, and Heyman have proposed an algorithm for computing the stationary vector of a Markov chain. Analysis by O'Cinneide confirmed the results of numerical experiments, proving that the GTH algorithm computes an approximation to the stationary vector with low relative error in each component. In this work, we develop a block form of the GTH(More)
