GammaRegularized

GammaRegularized[a, z]
is the regularized incomplete gamma function .

DetailsDetails

  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • In non-singular cases, .
  • GammaRegularized[a, z0, z1] is the generalized regularized incomplete gamma function, defined in non-singular 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.
