yn

 
 

Library: Bessel functions (OMBESSEL)
Import: ombessel.xmd
Return type: OMX

Returns: A Bessel function of the second kind: order n. Returns NaN for values of x that are <= 0.


Declaration

define external float function
     yn (value integer n, value float x)


Purpose

Use yn to calculate the Bessel function of the second kind (order n) for any value of x.

Example:


  import "ombessel.xmd" unprefixed
  import "omfloat.xmd" unprefixed
  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"
