gives the Kelvin function .

KelvinKer[n, z]
gives the Kelvin function .


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • For positive real values of parameters, . For other values, is defined by analytic continuation.
  • KelvinKer[n, z] has a branch cut discontinuity in the complex z plane running from to .
  • KelvinKer[z] is equivalent to KelvinKer[0, z].
  • For certain special arguments, KelvinKer automatically evaluates to exact values.
  • KelvinKer can be evaluated to arbitrary numerical precision.
  • KelvinKer automatically threads over lists.
