Numerical linear algebra for quaternions — fast, practical, and well‑tested. QuatIca was inspired by the pioneering work in quaternion linear algebra, particularly the QTFM (Quaternion Toolbox for ...
Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. Conventional reservoir flow field characterization methods are ...
Matrix inversion is a fundamental operation in linear algebra that allows you to solve linear equations and perform various transformations. In this article, we will explore the process of calculating ...
Matrix calculations are an essential part of various mathematical, scientific, and engineering applications. In this article, we will walk you through the process of calculating a matrix, including ...
We propose a new method for solving the spinless Salpeter equation. Choosing a special set of orthonormal basis functions we are able to calculate analytically the integral over the corresponding ...
Abstract: This paper firstly studies the intelligent application of matrix eigenvalues and eigenvalue methods based on tensor analysis. Then, starting from the concept of eigenvalues and eigenvectors ...
Hi! I'm trying to solve a generalized eigenvalue problem on huge 100kx100k sparse matrices (that are not generally positive definite). I'm using the default shift invert solver. The SparseLU solver ...
