DESIR

On the latest version of DESIR-II. We give a description of the latest version of the DESIR-II package (Barkaton and Jung, 1997; Pflügel, 1996a, b) implemented in Maple V. The purpose of this package is the computation of a fundamental set of formal solutions of nth-order linear differential equations, first-order linear differential systems and asymptotic representations of solutions of nth-order linear difference equations. Our package provides a detailed online-help and a set of additional tools for handling the computed results.
