Beir | R Documentation |
This function calculates the complex solution to the Kelvin differential
equation using modified Bessel functions of the first kind, specifically
those produced by BesselJ
.
Beir(x, ...)
## Default S3 method:
Beir(x, nu. = 0, nSeq. = 1, return.list = FALSE, ...)
Bei(...)
Ber(...)

Ber
and Bei
are wrapper functions
which return the real and imaginary components of Beir
, 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.
