WhittakerW

WhittakerW[k, m, z]
gives the Whittaker function W_(k,m)(z).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • WhittakerW is related to the confluent hypergeometric function by .
  • W_(k,m)(z) is infinite at z=0 for integer m>0.
  • For certain special arguments, WhittakerW automatically evaluates to exact values.
  • WhittakerW can be evaluated to arbitrary numerical precision.
  • WhittakerW[k, m, z] has a branch cut discontinuity in the complex z plane running from -∞ to 0.
