Analytic Subtraction Applied to the Incomplete Gamma and Beta Functions
Copyright policy )Analytic Subtraction Applied to the Incomplete Gamma and Beta Functions
The purpose of this paper is to draw attention to a method of performing analytic subtractions that can dramatically improve the numerical stability of a continued fraction (cf) or series expansion. The method is applied to the computation of the incomplete gamma and beta functions.
