  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • WhittakerM is related to the hypergeometric function by .
  • vanishes at for .
  • For certain special arguments, WhittakerM automatically evaluates to exact values.
  • WhittakerM can be evaluated to arbitrary numerical precision.
  • WhittakerM automatically threads over lists.
  • WhittakerM[k,m,z] has a branch cut discontinuity in the complex plane running from to .
