is the regularized incomplete gamma function .


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • In nonsingular cases, .
  • GammaRegularized[a,z0,z1] is the generalized regularized incomplete gamma function, defined in nonsingular cases as Gamma[a,z0,z1]/Gamma[a].
  • Note that the arguments in GammaRegularized are arranged differently from those in BetaRegularized.
  • For certain special arguments, GammaRegularized automatically evaluates to exact values.
  • GammaRegularized can be evaluated to arbitrary numerical precision.
  • GammaRegularized automatically threads over lists.
