If both arguments are arrays, their ranks and shapes shall conform.

Standard

Fortran 2008 and later

Class

Elemental function?

Syntax

result = bessel_yn(n, x)

Arguments

• n - Shall be a scalar or an array of type integer.
• x - Shall be a scalar or an array of type real.

Return value

The return value is a scalar of type real. It has the same kind as x.

Example

program test_besyn
  real(8) :: x = 1.0_8
  x = bessel_yn(5,x)
end program test_besyn
