GammaRegularized

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.
