This paper describes a new method of QR-decomposition of square nonsingular matrices (real or complex) by the Givens rotations through the unitary discrete heap transforms. This transforms can be ...

Department of Computer Science and Management. For N = 2 we have one matrix:. For N = 4 there are three matrices with integer entries: For N = 8 we have seven matrices with elements 0, ±1 [7]. in ...

The QR method is a numerical method that is used to calculate all eigenvalues of a matrix, without necessarily obtaining the eigenvectors at the same time. The QR method involves an iterative process ...

Abstract: Discrete orthogonal matrices have applications in information coding and cryptography. It is often challenging to generate discrete orthogonal matrices. A common approach widely in use is to ...

Abstract: This paper presents a novel combined method for analog circuit fault diagnosis based on dependence matrices and intelligent classifiers (DM-IC). The main purpose of this method is to obtain ...

This work presents two fast isogeometric formulations of the Boundary Element Method (BEM) applied to heat conduction problems, one accelerated by Fast Multipole Method (FMM) and other by Hierarchical ...

In order to generate simple, efficient analytical methods that are also fast, clean, and economical, and are capable of producing reliable results for a large number of samples, a micro scale ...
