In this paper we present a new and elementary approach for proving the main results of Katz (1996) using the Jordan-Pochhammer matrices of Takano andBannai (1976) andHaraoka (1994). We find an explicit version of the middle convolution of Katz (1996) that connects certain tuples of matrices in linea

✦ Synopsis
In this paper, we will use the Schur algorithm to compute a solution to the Kaftal-Larson-Weiss mixed (H^{2}-H^{\infty}) problem in the Nehari setting. First we will use the Schur algorithm to solve a mixed (H^{2}-H^{\infty}) Carathéodory interpolation problem. By passing limits, we will then obtain an explicit formula in terms of Hankel matrices to solve the rational (H^{2}-H^{\infty}) Nehari problem. Explicit solutions in terms of minimal state space realization will be given. 1993 Academic Press, Inc.

It is shown that individual (state-to-state) S-matrix elements can be generated from the 1,l element of the inverse of a small tridiagonal matrix. The tridiagonal matrix is produced via the Lanczos algorithm from discretized integral equations for the amplitude density. The convergence of 1 S,., I\*
