Library: ombessel - Bessel functions
Include: ombessel.xin |
Return type: Opaque Returns: A Bessel function of the second kind: order n. Returns NaN for values of x that are <= 0. |
define external float function
yn (value integer n, value float x)
Use yn to calculate the Bessel function of the second kind (order n) for any value of x.
Example:
include "ombessel.xin"
process
local integer x initial {2}
local float y initial {17.5}
local float yn-bessel
set yn-bessel to yn (x, y)
output "A yn Bessel function of the first kind, order "
|| "d" % x
|| ", of "
|| "d" % y
|| " = "
|| "d" % yn-bessel
|| "%n"
; Output: "A yn Bessel function of the first kind, order 2, of 17.5 = 0.171676655217493"
