Inversion and factorization of non-Hermitian quasi-Toeplitz matrices
Algorithms for the factorization of quasi-Toeplitz Hermitian matrices are generalized to non-Hermitian matrices. The authors show that the algorithms are related to a pair of lattices, this makes the theory more intuitive and helps the overall understanding. New inversion formulas are given.
