Purpose of use
To verify my own results for function I am coding to facilitate another calculation. My results matched except for a = negative integer, but I found an error and now we match for all a and x. I also require complex a and x. Mathematica formulas at functions.wolfram.com/GammaBetaErf/Gamma2/03/01/02/ show how to compensate for branch cuts.
Comment/Request
please disregard previous suspicion of an error -- found a bug in my code.

Purpose of use
Looking for how to compute the value of incomplete gamma functions.
Comment/Request
Could you please provide the relevant formula that can be used in a comptuer program to evaluate the function?
