28 October 1994 Look-ahead Schur-type algorithm for solving general Toeplitz systems
Author Affiliations +
The classical fast Toeplitz solvers, such as the Levinson algorithm and Schur-type algorithms, require that all leading principal submatrices of the Toeplitz matrix be nonsingular, and they are numerically unstable for general Toeplitz systems. We present a Schur-type algorithm with look-ahead that can be applied to general Toeplitz systems with singular and nonsingular, but ill-conditioned leading principal submatrices.
