Abstract: During the development of fuel cell hybrid electric vehicle, it is crucial to obtain real-time information on the physical distribution within the fuel cell stack to ensure the consistency ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Abstract: Computing three-phase short-circuit currents (3pSCCs) in large-scale high-voltage power systems needs to find the inverted nodal admittance matrix, which is generally time- consuming.

In 1999, The Matrix premiered in theaters and wowed audiences across the world. It was followed by two sequels, The Matrix Reloaded and The Matrix Revolutions, in 2002 and 2003, respectively. But it ...

What we're trying to test is that the Mumps requires more memory than it initially predicts. Maybe Mumps has improved its memory prediction for this type of matrix (tridiagonal) to realize that it ...

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 ...

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 ...

In the current article we propose a new efficient, reliable and breakdown-free algorithm for solving general opposite-bordered tridiagonal linear systems. An explicit formula for computing the ...

A new method for solving the 1D Poisson equation is presented using the finite difference method. This method is based on the exact formulation of the inverse of the tridiagonal matrix associated with ...

Currently, eig and similar throw no method eigfact when applied to these types of matrices. We should be able to provide efficient LAPACK-based solvers for these types. For Tridiagonal, we can exploit ...
