NEP_MiniMax: An Approach for NEPs Based on Matrix-valued Minimax Approximations

Chenkun Zhang, Jiawei Gu, Lei-Hong Zhang

We propose NEP_MiniMax, a novel computational method for solving nonlinear eigenvalue problems (NEPs) $T(\hat{I}»)\mathbf{u}=0$ on compact continua $\hat{I}\text{c◯}\subset \mathbb{C}$. The method co…
