This function calculates the complex solution to the Kelvin differential
equation using modified Bessel functions of the *second kind*, specifically
those produced by `BesselK`

.

`x` |
numeric; values to evaluate the complex solution at |

`...` |
additional arguments passed to |

`nu.` |
numeric; value of |

`nSeq.` |
positive integer; equivalent to |

`add.tol` |
logical; Should a fudge factor be added to prevent an error for zero-values? |

`return.list` |
logical; Should the result be a list instead of matrix? |

`show.scaling` |
logical; Should the normalization values be given as a message? |

`Ker`

and `Kei`

are wrapper functions
which return the real and imaginary components of `Keir`

,, respectively.

If `return.list==FALSE`

(the default),
a complex matrix with as many columns as using `nSeq.`

creates.
Otherwise the result is a list with matrices for
Real and Imaginary components.
