• GammaRegularized[a, z] is the regularized incomplete gamma function .
• Mathematical function (see Section A.3.10
• In non-singular cases,
• GammaRegularized[a, , ]
is the generalized regularized incomplete gamma function, defined in non-singular cases as Gamma[a, , ]/Gamma[a]
• Note that the arguments in GammaRegularized
are arranged differently from those in BetaRegularized
