A rational Arnoldi process with applications

Summary The rational Arnoldi process is a popular method for the computation of a few eigenvalues of a large non‐Hermitian matrix A∈Cn×n and for the approximation of matrix functions. The method is particularly attractive when the rational functions that determine the process have only few distinct...
