The core-EP inverse: A numerical approach for its acute perturbation

Mengmeng Zhou, Jianlong chen, Nestor Thome

This paper studies the concept of stable perturbation $B\in {\mathbb{C}}^{n\times n}$ for the core-EP inverse of a matrix $A\in {\mathbb{C}}^{n\times n}$ with index $k$. For a given stab…
