Abstract:
Analytical formulas through the initial values suitable for numerical computation are developed for the exponential integral functions En (x). The relationships obtained are numerically stable for all values of n and for x < 1. Numerical results are also given.PACS No: 31.15.+q, 31.20.Ej AMS subject classification:81-V55, 81V45
