Solving Linear Inequalities In A Least Squares Sense
. In 1980, Han [6] described a finitely terminating algorithm for solving a system Ax b of linear inequalities in a least squares sense. The algorithm uses a singular value decomposition of a submatrix of A on each iteration, making it impractical for ...

A preconditioned Krylov subspace method for the solution of least squares problems
We present an iterative method of preconditioned Krylov type for the solution of large least squares problems. We prove that the method is robust and investigate its rate of convergence.

HILBERT-SPACE TECHNIQUES FOR SPECTRAL REPRESENTATION IN TERMS OF OVERCOMPLETE BASES
Topics associated with the representation of objects from a separable Hilbert space in terms of an a priori given overcomplete system (dictionary) of its generators (atoms) are handled. First the procedure of nding such a representation is formulated and

Communication Avoiding Rank Revealing QR Factorization with Column Pivoting
. In this paper we introduce CARRQR, a communication avoiding rank revealing QR factorization with tournament pivoting. We show that CARRQR reveals the numerical rank of a matrix in an analogous way to QR factorization with column pivoting (QRCP ...

Many problems based on unstructured grids provide a natural multigrid framework due to using an adaptive gridding procedure. When the grids are saved, even starting from just a ne grid problem poses no serious theoretical di culties in applying multigrid.

ESTIMATING THE CONSUMPTION MATRIX FROM INEXACT DATA IN THE LEONTIEF MODEL
. The Leontief model, originally developed for describing an economic system in terms of mutually interrelated and structurally conditioned simultaneous flows of commodities and services, has important applications to wide ranging disciplines.
