Library: ombessel - Bessel functions
 Include: ombessel.xin  | 
Return type: OMX Returns: A Bessel function of the first kind: order 1.  | 
  define external float function
       j1 value float x
Use j1 to calculate the Bessel function of the first kind (order 1) for any value of x.
Example:
  include "ombessel.xin"
  process
     local float x initial {17.5}
     local float j1-bessel
     set j1-bessel to j1 (x)
     output "A j1 Bessel function of "
         || "d" % x
         || " = "
         || "d" % j1-bessel
         || "%n"
  ; Output: "A j1 Bessel function of 17.5 = -0.16341996942575"
