Two Algorithms for Solving A General Backward Pentadiagonal Linear Systems

In this paper we present an efficient computational and symbolic algorithms for solving a backward pentadiagonal linear systems. The implementation of the algorithms using Computer Algebra Systems (CAS) such as MAPLE, MACSYMA, MATHEMATICA, and MATLAB are straightforward. An examples are given in order to illustrate the algorithms. The symbolic algorithm is competitive the other methods for solving a backward pentadiagonal linear systems.
