WebOct 1, 2003 · An apparently new expansion of the exponential integral E1 in incomplete gamma functions is presented and shown to be a limiting case of a more general expansion given by Tricomi in 1950 without proof. This latter expansion is proved here by interpreting it as a “multiplication theorem”. A companion result, not mentioned by THcomi, holds ... Webconvenient since several well known functions are special cases of the incomplete gamma function. We include a double precision FORTRAN 77 implementation. §0. Introduction In this paper we present a general algorithm, along with a working FORTRAN 77 implementation, to calculate the incomplete gamma function Γ(α,x).
