A Test Matrix Generation

چکیده

We discuss the design and implementation of a suite of test matrix generators for testing linear algebra software. These routines generate random matrices with certain properties which are useful for testing linear equation solving, least squares, and eigendecomposition software. These properties include the spectrum, symmetry, bandwidth, norm, sparsity, conditioning (with respect to inversion or for the eigenproblem), type (real or complex), and storage scheme (dense, packed, or banded).

A Direct Matrix Inversion-Less Analysis for Distribution System Power Flow Considering Distributed Generation

This paper presents a new direct matrix inversion-less analysis for radial distribution systems (RDSs). The method can successfully deal with weakly meshed distribution systems. (WMDSs). Being easy to implement, direct methods (DMs) provide an excellent performance. Matrix inversion is the mean reason of divergence and low-efficiency in power flow algorithms. In this paper, the performance of t...

Investigation of Brownian Motion of CuO-Water Nanofluid in a Porous Cavity with Internal Heat Generation by Using of LTNE Model

In this paper, the effect of the Brownian term in natural convection of CuO-Water nanofluid inside a partially filled porous cavity, with internal heat generation has been studied. It is assumed that the viscosity and thermal conductivity of nanofluid consists of a static part and a Brownian part of which is a function of temperature and the volume fraction of nanofluid. Because of internal hea...

SISSA 34/2004/EP hep-ph/0405237 Nuclear Matrix Elements of 0νββ-Decay: Possible Test of the Calculations

A possible model independent test of the theoretically calculated nuclear matrix elements of 0νββ-decay is proposed. The test can be accomplished if 0νββ-decay of three (or more) nuclei is observed. The selection of the nuclei for the next generation of 0νββ-decay experiments should be done taking into account also considerations regarding the possibility to test the nuclear matrix element calc...
