Abstract This paper analyses the performance of several versions of a block parallel
algorithm in order to apply Neville elimination in a distributed memory parallel computer.
Neville elimination is a procedure to transform ...
The Cosmic Microwave Background (CMB) is a diffuse radiation which is contaminated by the radiation emitted by point sources. The precise knowledge of CMB fluctuations can lead to a better knowledge of the chemistry at the ...

NnmfPack is a library for the nonnegative matrix factorization (NNMF) problem. Nowadays NNMF is an essential tool in many fields spanning machine learning, data analysis, image analysis or audio source separation, among ...
[EN] This paper describes several parallel algorithmic variations of the Neville elimination. This elimination solves a system of linear equations making zeros in a matrix column by adding to each row an adequate multiple ...
Abstract
In this work we present a suitable computational tool to deal with large
matrices and solve systems of non-linear equations. This technique is applied to a
very interesting problem: the detection and flux ...
