Recently, in order to find the principal moments of inertia of a large number of rigid bodies, it was necessary to compute the eigenvalues of many real, symmetric 3 × 3 matrices. The available ...

Huawei unveiled the Mate XT Ultimate in China, just a day after the iPhone 16 Pro launch. While Apple introduced incremental upgrades, Huawei has pushed boundaries with an already novel form factor.

Abstract: It is known that the worst case near-far resistance of optimum multiuser detectors for asynchronous Gaussian multiple-access channels can be expressed in terms of a class of ...

Toeplitz tridiagonal matrix; Crout’s method; tridiagonal and diagonally dominant matrix For example, in Meurant’s paper 16 some results concerning the characterization of inverses of symmetric ...

Abstract: The matrix eigenvalue inverse problem is the problem of inversely determining the matrix by using the information of the known eigenvalues and eigenvectors and other constraints. The matrix ...

Identification of alcoholism is clinically important because of the way it affects the operation of the brain. Alcoholics are more vulnerable to health issues, such as immune disorders, high blood ...

We put forward and prove a simple theorem stating that the eigenvalues of a tridiagonal matrix change their sign (as a set), once the signs of the diagonal elements of the matrix are changed. We also ...
