combine

eve::combine = functor<combine_t>

inlineconstexpr

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   template<simd_value W>
   typename W::combined_type combine(W a, W b) noexcept;
}

Parameters

• a, b: two SIMD values of the same type and cardinal

Return value

• A SIMD value contains the parameters concatenation, thus producing a register of twice as many elements.

Example

#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};
 
  auto pf2 = eve::combine(pf,pf);
  std::cout << "pf                  ---> "  << pf << "\n";
  std::cout << "eve::combine(pf,pf) ---> "  << pf2 << "\n";
}
