Abstract
Let T R be a positive Toeplitz matrix with a rational symbol T R . In this chapter, we will use the finite sections T R,n of T R to compute the maximal outer spectral factor and the unitary part for TR. Then we shall use the lower triangular Cholesky factorization of T R,n to approximate the Taylor’s coefficient of the maximal outer spectral factor for T R .
