The Look-Ahead Lanczos Process for Large Nonsymmetric Matrices and Related Algorithms large non-Hermitian linear systems. However, the Lanczos algorithm in its original form is susceptible to possible breakdowns and potential instabilities. We describe a look-ahead variant of the Lanczos process that remedies the problems of the original algorithm. We also discuss related algorithms

Adaptive Signal Processing with Emphasis on QRD-Least Squares Lattice. The algorithm makes it possible for the filter to perform satisfactorily in an environment when complete knowledge of the relevant signal characteristics is not available , Adaptive filters find applications in such diverse fields as communications, radar, sonar, control, and biomedical enginee

A Direct Method for Reordering Eigenvalues in the Generalized Real Schur form of a Regular Matrix Par matrix pair (.) is presented. Each swap of two adjacent eigenvalues (real, or complex conjugate pairs) involves solving a generalized Sylvester equation and the construction of two orthogonal transformation matrices from certain eigenspaces associated with the corresponding diagonal blocks. An err

Computing the Singular Value Decomposition on a Fat-Tree Architecturen necessary to calculate the SVD in real time. We present here a new technique for computing the SVD on a parallel architecture whose processors are connected via a fat-tree. We tested our idea on the Connection Machine CM-5, and achieved efficiency up to 40% even for moderately sized matrices.

Determining Rank in the Presence of Errorsition and make a decision about the rank by examining the small elements of the decomposition. In this paper we look at three commonly use decompositions: the singular value decomposition, the pivoted QR decomposition, and the URV decomposition.

Some Linear Algebra Issues in Large-Scale Optimizationrisingly wide variation not only in form and representation of matrices, but also in the level of solution accuracy. A broad and often vaguely specified concept in the latter context is “inexact” solution. For unconstrained, linearly constrained and nonlinearly constrained optimization in turn, we d
