Chebychev interpolations of the Gamma and Polygamma Functions and their analytical properties

Karl Dieter Reinartz

Published 2016-05-02Version 1

Chebychev approximations are given for the Gamma and the Polygamma functions in only one contiguous intervall [1..inf] with a definable maximal relative error. The approximations need about three coefficients per decimal until a checked precision of 100 decimal digits.
