SYNTAX
o result = bessel_yn(n, x) o result = bessel_yn(n1, n2, x)
DESCRIPTION
bessel_yn(n, x) computes the [[Bessel function]] of the second kind of order N of X. If N and X are arrays, their ranks and shapes shall conform.
bessel_yn(n1, n2, x) returns an array with the [[Bessel function|Bessel functions]] of the first kind of the orders N1 to N2.
ARGUMENTS
N - Shall be a scalar or an array of type INTEGER. N1 - Shall be a non-negative scalar of type INTEGER. N2 - Shall be a non-negative scalar of type INTEGER. X - Shall be a scalar or an array of type REAL; for bessel_yn(n1, n2, x) it shall be scalar.
RETURN VALUE
The return value is REAL. It has the same kind as X.
EXAMPLE
Sample program:
program demo_besyn real(8) :: x = 1.0_8 x = bessel_yn(5,x) end program demo_besyn
STANDARD
[[Fortran 2008]] and later
CLASS
[[Elemental function]], except for the transformational function bessel_yn(n1, n2, x)
