ABSTRACT: In this paper, we consider the model updating problem of the undamped vibroacoustic system with no spill-over (MUP-UVA), which is to update the original system to a new system such that some ...
A matrix is a rectangular arrangement of numbers into rows and columns. It is usually represented by capital letters (A, B, C, …) and its individual elements by lowercase letters accompanied by ...
Rank is an essential concept in linear algebra that represents the number of linearly independent rows or columns of a matrix. It plays a crucial role in solving linear equations, determining the null ...
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 ...
