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.
  • See the Mathematica book: Section 3.2.10.
