gives the Whittaker function .


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