BesJN Intrinsic

     BesJN(N, X)
     

BesJN: REAL function, the KIND= value of the type being that of argument X.

N: INTEGER not wider than the default kind; scalar; INTENT(IN).

X: REAL; scalar; INTENT(IN).

Intrinsic groups: unix.

Description:

Calculates the Bessel function of the first kind of order N of X. See bessel(3m), on whose implementation the function depends.
