Calculates the Modified Bessel Function of arbitrary order. Determines I_n(x) e^(-x) instead of I_n(x) to avoid large argument problems.

Arguments

Type IntentOptional Attributes Name
integer(kind=I4B), intent(in) :: n

Order of Modified Bessel Function.
real(kind=SP), intent(in) :: x

Order of Modified Bessel Function.

Return Value real(kind=SP)

Returned value of the Bessel Function calculation.
