A new investigation of the extended Krylov subspace method for matrix function evaluations


For large square matrices A and functions f , the numerical approximation of the action of f(A) to a vector v has received considerable attention in the last two decades. In this paper we investigate the Extended Krylov subspace method, a technique that was recently proposed to approximate f(A)v for A symmetric. We provide a new theoretical analysis of the… (More)
