The partial-fractions expansion of a function F(s)/(s-a)<sup>m</sup>, m > 1, involves the computation of m coefficients, namely (1 /i!)(d<sup>i</sup>F(a)/ds<sup>i</sup>), 0 = i = m-1. Wehrhahn [1] and Karni [3] have provided a method for computing these coefficients algebraically. A new approach is taken here which involves approximating a multiple pole by neighboring simple poles. The theory deve
