Description

bessel_j1(x) computes the(削除) Bessel (削除ここまで)(削除) function (削除ここまで)(削除) of (削除ここまで)(削除) the (削除ここまで)(削除) first (削除ここまで)(削除) kind (削除ここまで)(削除) of (削除ここまで)(削除) order (削除ここまで)(削除) 1 (削除ここまで)(削除) of (削除ここまで)(追記) Bessel function (追記ここまで)(追記) of the first kind of order 1 of (追記ここまで)x.

Standard

(削除) Fortran 2008 (削除ここまで)(追記) Fortran 2008 (追記ここまで)(追記) and later (追記ここまで)

Class

(削除) Elemental function (削除ここまで)(追記) Elemental function (追記ここまで)

Syntax

result = bessel_j1(x)

Arguments

• x - The type shall be real, and it shall be scalar.

Return value

The return value is of type real and it lies in the range - 0.5818... \\leq Bessel (0,x) \\leq 0.5818 . It has the same kind as x.

Example

program test_besj1
 real(8) :: x = 1.0_8
 x = bessel_j1(x)
end program test_besj1
