• Nearly penta-diagonal matrices
• Nonsingular
• Sherman-Morrison-Woodbury formula
• Inverse

In this paper, a new efficient computational algorithm is presented for solving nearly penta-diagonal linear systems based on the use of any penta-diagonal linear solver. The implementation of the algorithm using computer algebra systems (CAS) such as MAPLE and MATLAB is straightforward. Numerical examples are given to illustrate the effectiveness of our method.
