Barycentric Padé approximation
Published 16 Jul 2013 in math.NA | (1307.4245v2)
Abstract: In this paper, we show how any Pad\'e approximant $[p/q]_f$ of a formal power series $f$ can be written under two different barycentric rational forms. These form depend on $p+q+1$ parameters which can be almost arbitrarily chosen.
