A fast and reliable algorithm for evaluating nth order pentadiagonal determinants
نویسنده
چکیده
In the current article we present a fast and reliable algorithm for evaluating nth order pentadiagonal determinants in linear time. It is a natural generalization of the DETGTRI algorithm [M. El-Mikkawy, A fast algorithm for evaluating nth order tri-diagonal determinants, J. Comput. Appl. Math. 166 (2004) 581–584]. The algorithm is suited for implementation using computer algebra systems (CAS) such as MACSYMA and MAPLE. Some illustrative examples are given. 2008 Elsevier Inc. All rights reserved.

متن کاملInversion of general tridiagonal matrices
In the current work, the authors present a symbolic algorithm for finding the inverse of any general nonsingular tridiagonal matrix. The algorithm is mainly based on the work presented in [Y. Huang, W.F. McColl, Analytic inversion of general tridiagonal matrices, J. Phys. A 30 (1997) 7919–7933] and [M.E.A. El-Mikkawy, A fast algorithm for evaluating nth order tridiagonal determinants, J.

متن کاملOn Solving Pentadiagonal Linear Systems via Transformations
Many authors studied numeric algorithms for solving the linear systems of the pentadiagonal type. The well-known Fast Pentadiagonal System Solver algorithm is an example of such algorithms. The current article is describes new numeric and symbolic algorithms for solving pentadiagonal linear systems via transformations. New algorithms are natural generalization of the work presented in [Moawwad ...
متن کاملA parallel method for solving pentadiagonal systems of linear equations
A new parallel approach for solving a pentadiagonal linear system is presented. The parallel partition method for this system and the TW parallel partition method on a chain of P processors are introduced and discussed. The result of this algorithm is a reduced pentadiagonal linear system of order P 2 compared with a system of order 2P 2 for the parallel partition method. More importantly the n...
متن کاملSymbolic algorithm for inverting cyclic pentadiagonal matrices recursively - Derivation and implementation
In this paper, by using parallel computing along with recursion, we describe a reliable symbolic computational algorithm for inverting cyclic pentadiagonal matrices. The algorithm is implemented in MAPLE. Two other symbolic algorithms are developed and the computational costs for all algorithms are given. An example is presented for the sake of illustration. © 2009 Elsevier Ltd. All rights rese...
