Description

The six Mathematica notebooks (extension "nb"), contain different algorithms to calculate the exponential integral Ei(X) and its inverse. The methods and all details are provided in the manuscript "The exponential integral Ei(x) and numerical calculation of its inverse", by Ricker & Singull (under review). For just inspecting the code, without the Mathematica software, the notebooks are provided also as PDF files.
