Abstract

In this paper, an efficient computational algorithm for the exponential integral )(zEυ was established for all 21qiqv+= and biaz+=. The algorithm based on the evaluation of the continued fraction expansion of )(zEυ. Numerical applications of the algorithm are also given together with 3D plotes.
