Equivalences for Linearizations of Matrix Polynomials

Robert M. Corless, Leili Rafiee Sevyeri, B. David Saunders

One useful standard method to compute eigenvalues of matrix polynomials $\mathbf{P}(z)\in {\mathbb{C}}^{n\times n}[z]$ of degree at most $\ell$ in $z$ (denoted of grade $\ell$, for sho…
