bessel_y1(3f) - [FORTRAN:INTRINSIC:MATHEMATICS] Bessel function of the second kind of order 1
result = bessel_y1(x)
bessel_y1(x) computes the [[Bessel function]] of the second kind of order 1 of X.
X The type shall be REAL.
The return value is REAL. It has the same kind as X.
Sample program:
program demo_besy1 use, intrinsic :: iso_fortran_env, only : real_kinds, & & real32, real64, real128 implicit none real(kind=real64) :: x = 1.0_real64 x = bessel_y1(x) end program demo_besy1
