摘要：
In this paper we consider pentadiagonal (n + 1) x (n + 1) matrices with two sub-diagonals above and below the main diagonal at distances k and l from the main diagonal where 1 <= k < l <= n. We give explicit formulae for the eigenpairs of imperfect Toeplitz matrices in the case when (n + 1)/2 <= k. Imperfectness means that the first and last k elements of the main diagonal differ from the elements in the middle. (C) 2020 Elsevier Inc. All rights reserved.
