I'm confused by the swapping parameters aspect, perhaps because I have not used Mathematica for nearly two decades. Could we forget about gammainc functions in MATLAB and Mathematica for a moment and just tell me the integral you want to evaluate and the ranges of the two parameters that you...
A very accurate complex Gamma function valid over the entire complex plane. This function is more accurate than MATLAB's own real only Gamma function.Cite As Paul Godfrey (2025). Gamma (https://www.mathworks.com/matlabcentral/fileexchange/3572-gamma), MATLAB Central File Exchange. Retrieved ...

The gamma function Γ(a) is defined by Γ(a)=∫∞0ta−1e−tdt. MATLAB® uses the regularized or normalized definition of the incomplete gamma function, where P(x,a)+Q(x,a)=1. The scaled lower and upper incomplete gamma function are defined by Ps(x,a)=Γ(a+1)Γ(a)exxa∫x...
Vout=AVγin Vin:非负实数值,比如为图像像素; A:某一常数,通常情况下取值为 1,输入输出的范围一般为 [0, 1]; γ<1:光照强度变强,称为 gamma compression γ>1:光照强度变弱,称为 gamma expansion function gammaCorrection(name, a, gamma)

伽马函数《The gamma function》 This brief monograph on the gamma function was designed by the author to fill what he perceived as a gap in the literature of mathematics, which often treated the gamma function in a manner he described as both sketchy and overly complicated. Author Emil Artin,...
