  • Abstract
    An efficient algorithm is presented for the reliable computation of frequency response matrices of the form P(j\\omega I-A)^{-1}Q . Efficiency is achieved through an initial reduction of A to upper Hessenberg form H so that ( j\\omega I-H ) remains upper Hessenberg as ω is varied over a desired range. Linear systems with upper Hessenberg coefficient matrices can then be solved easily and accurately.
