In this paper, by using a special matrix factorization, a symbolic computational algorithm is developed to solve the cyclic penta-diagonal linear system. The algorithm is suitable for implementation using Computer Algebra Systems (CASs) such as MATLAB, MATHEMATICA and MAPLE. In addition, an efficient way of evaluating the determinant of a cyclic… (More)

In this paper, we consider an inverse problem with the k-tridiagonal Toeplitz matrices. A theoretical result is obtained that under certain assumptions the explicit inverse of a k-tridiagonal Toeplitz matrix can be derived immediately. Two numerical examples are given to demonstrate the validity of our results. (c) ٢٠١٢ Elsevier Ltd. All rights reserved.… (More)

Very recently, an efficient computational algorithm (DETQPT algorithm) for the determinant evaluation of general cyclic pentadiagonal Toeplitz matrices has been proposed by Y.L. Jiang and J.T. Jia (J. Math. Chem. 51: 2503-2513, 2013). In this paper, an explicit formula for the determinant of a cyclic pentadiagonal Toeplitz matrix is derived at first. Then,… (More)
