Abstract
In this paper, an inversion algorithm for a banded matrix is presented. The nn twisted decompositions of a banded matrix are given first; then the inverse of the matrix is obtained, one column at time. The method is about two times faster than the standard method based on the LULU decomposition, as is shown with the analysis of computing complexity and the numerical experiments.
