In this paper we discuss a recursive divide and conquer algorithm to compute the inverse of an unreduced tridiagonal matrix. It is based on the recursive application of the Sherman Morrison formula to a diagonally dominant tridiagonal matrix to avoid numerical stability problems. A theoretical study
