Abstract
Motivated by current applications of the bordered tridiagonal matrices of large order, the infinite invertible bordered tridiagonal matrices are considered. These matrices are a generalization of the tridiagonal and the arrowhead matrices. A method based on a simple but suitable factorization is proposed for obtaining, in the finite-dimensional case, a decomposition of the inverse. This procedure can be applicable to infinite bordered tridiagonal matrices. Some illustrative examples are given.
