cyl_bessel_h1n

kyosu::cyl_bessel_h1n = {}

inlineconstexpr

Computes the Bessel/Hankel functions of the third kind, \( H_n^{(1)}(z) = J_n(z)+iY_n(z)\).

#include <kyosu/functions.hpp>

Callable Signatures

namespace kyosu
{
   template<kyosu::concepts::cayley_dickson T> constexpr auto cyl_bessel_h1n(int n, T z) noexcept;
   template<eve::floating_ordered_value T>     constexpr auto cyl_bessel_h1n(int n, T z) noexcept;
}

Parameters

• z: Value to process.

Return value

• returns \(H_n^{(1)}(z)\).

Example
