◆ asec

kyosu::asec = {}
inlineconstexpr

Computes the arcsecant of the argument.

Defined in Header

#include <kyosu/functions.hpp>

Callable Signatures

namespace kyosu
{
template<eve::floating_ordered_value T> constexpr auto asec(T z) noexcept; //1
template<kyosu::concepts::cayley_dickson T> constexpr auto asec(T z) noexcept; //2
}
constexpr tags::callable_asec asec
Computes the arcsecant of the argument.
Definition: asec.hpp:79
Main KYOSU namespace.
Definition: types.hpp:14

Parameters

  • z: Value to process.

Return value

  1. a real input z is treated as if kyosu::complex(z) was entered.
  2. Returns elementwise \(\mathop{\mathrm{acos}}(1/z)\).

Example

#include <kyosu/kyosu.hpp>
#include <eve/wide.hpp>
#include <iostream>
int main()
{
using wide_ft = eve::wide <float, eve::fixed<4>>;
wide_ft ref1 = { 3.0f, 2.0f, 1.0f, 0.5f};
wide_ft imf1 = { 2.0f , -1.0, -5.0, 0.0};
wide_ft ref2 = { 0.0, 1.0, 2.0, 3.0};
auto zc = kyosu::complex_t<wide_ft>(ref1, imf1);
std::cout
<< "---- simd" << std::endl
<< "<- zc = " << zc << std::endl
<< "-> asec(zc) = " << kyosu::asec(zc)<< std::endl
<< "-> asec(ref2) = " << kyosu::asec(ref2) << std::endl;
return 0;
