    Purpose of use
    To make production forecasts using a model called stretched exponential decline model, some formulas of the model use the gamma and the gamma incomplete function. I use to check the results I got using python and scipy.
    Comment/Request
    Very good calculator I always use to check the results obtained with others packages.

    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.
