Abstract: This paper proposes a novel approximation for the exponential integral function, E 1 [x], using a sum of exponential functions. This approximation ...
It would be nice if the following function (or some slight variation thereof) could be included in scipy.special so as to permit the computation of the exponential integral of complex arguments: ...
