Abstract

Abstract: In this paper, we will derive a solver for a symmetric strongly nonsingular higher order generator representable semiseparable plus band matrix. The solver we will derive is based on the Levinson algorithm, which is used for solving strongly nonsingular Toeplitz systems. In the first part an solver for a semiseparable matrix of semiseparability rank p is derived, and in a second part we derive an solver for a band matrix with bandwidth . Both solvers are constructed in a similar way: firstly a Yule–Walker-like equation needs to be solved, and secondly this solution is used for solving a linear equation with an arbitrary right-hand side. Finally, a combination of the above methods is presented to solve linear systems with semiseparable plus band coefficient matrices. The overall complexity of this solver is plus lower order terms. In the final section numerical experiments are performed. Attention is paid to the timing and the accuracy of the described methods. [Copyright &y& Elsevier]

Abstract

The article discusses the decrease of paper consumption in business processes. Replacement of paper-based systems with electronic ones had caused the decrease in cut-paper sales. Workflows have been redesigned to reduce or eliminate paper-centric processes and was replace with more efficient ones through technologies such as Electronics Data Interchange and web services, imaging and electronic documents and document management systems. But in other firms such as Sonora Quest Laboratories in Tempe, Arizona, the use of paper based output is more likely to expand since health care providers prefer a printout of medical test lab results.
