Abstract
The purpose of this paper is to develop a novel approach to the problem of spectral factorization of matrix-valued functions. The key idea first appeared in Georgiou and Khargonekar [15], [16] where results were obtained for the scalar case. We exploit a version of the Nevanlinna-Pick algorithm that applies to matrix-valued functions and we make use of results in interpolation theory with matrix-valued functions analytic on The unit disc.
