function  

j1

 
 

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

A Bessel function of the first kind: order 1.


Declaration

  export external float function
       j1 value float x


Purpose

Use j1 to calculate the Bessel function of the first kind (order 1) for any value of x.

Example:

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