Extended Rate, more GFUN

Abstract

We present a software package that guesses formulas for sequences of, for example, rational numbers or rational functions, given the first few terms. Thereby we extend and complement Christian Krattenthaler’s program $\mathtt{Rate}$ and the relevant parts of Bruno Salvy and Paul Zimmermann’s $\mathtt{GFUN}$.
