Description

bessel_j0(x) computes the Bessel function of the first kind of order 0 of x.

Standard

Fortran 2008 and later

Class

Elemental function

Syntax

result = bessel_j0(x)

Arguments

• x - The type shall be real.

Return value

The return value is of type real and lies in the range - 0.4027... \\leq Bessel (0,x) \\leq 1$- 0.4027... \leq Bessel (0,x) \leq 1$. It has the same kind as x.

Example

program test_besj0
  real(8) :: x = 0.0_8
  x = bessel_j0(x)
end program test_besj0
