Abstract

In this paper we explore a numerical approach of the powers of doubly Leslie matrices, through the Fibonacci-Horner method and also using a determinantal form. Two algorithms for computing the entries of the powers of doubly Leslie matrix are built. In addition, Python programs are designed for both of these approaches. For illustrative purpose, some examples and applications are provided.
