| dc.description.abstract | A divide-and-conquer implementation of a generalized Schur algorithm enables (exact and) least-squares solutions of various block-Toeplitz or Toeplitz-block systems of equations with O(alpha-3n log2n) operations to be obtained, where the displacement rank-alpha is a small constant (typically between two to four for scalar near-Toeplitz matrices) independent of the size of the matrices. | - |
