Abstract
In this paper we consider the numerical approximation of \(A^{\alpha }\) by contour integral. We are mainly interested to the case of \(A\) representing the discretization of the first derivative by means of a backward differentiation formula, and \( 0\!<\!\alpha \!<\!1\). The computation of the contour integral yields a rational approximation to \(A^{\alpha }\) which can be used to define \(k\)-step formulas for the numerical integration of Fractional Differential Equations.
