conj

eve::conj = {}

inlineconstexpr

Computes the the conjugate value.

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   template< eve::value T >
   T conj(T z) noexcept;
}

Parameters

• z : real or complex argument.

Return value

Returns the conjugate of its argument. For real inputs the call reduces to identity.

Example

#include <eve/module/core.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
using wide_ft = eve::wide<float, eve::fixed<4>>;
 
int main()
{
  wide_ft pf = {-1.0f, 2.0f, -3.0f, -32768.0f};
 
  std::cout << "---- simd" << '\n'
            << "<- pf                   = " << pf << '\n'
            << "-> conj(pf)             = " << eve::conj(pf) << '\n';
 
  float        xf = -32768.0f;
 
  std::cout << "---- scalar" << '\n'
            << "<- xf                   = " << xf << '\n'
            << "-> conj(xf)             = " << eve::conj(xf) << '\n';
  return 0;
}

Semantic Modifiers

• Masked Call

  The call eve;conj[mask](x) provides a masked version of eve::conj which is equivalent to if_else (mask, conj(x), x).

  Example

  #include <eve/module/core.hpp>
  #include <eve/wide.hpp>
  #include <iostream>
   
  using wide_it = eve::wide<float, eve::fixed<4>>;
   
  int main()
  {
    wide_it pi = {-1, 2, -3, -18};
   
    std::cout << "---- simd" << '\n'
              << "<- pi                  = " << pi << '\n'
              << "-> conj[pi > -2](pi)  = " << eve::conj[pi > -2](pi) << '\n';
    return 0;
  }
