KokkosFFT::ihfft

template<typename ExecutionSpace, typename InViewType, typename OutViewType>
void KokkosFFT::ihfft(const ExecutionSpace &exec_space, const InViewType &in, const OutViewType &out, KokkosFFT::Normalization norm = KokkosFFT::Normalization::backward, int axis = -1, std::optional<std::size_t> n = std::nullopt)

Inverse of hfft.

Template Parameters:

  • ExecutionSpace – The type of Kokkos execution space

  • InViewType – Input View type for the fft

  • OutViewType – Output View type for the fft

Parameters:

  • exec_space – [in] Kokkos execution space

  • in – [in] Input data (real)

  • out – [out] Output data (complex)

  • norm – [in] How the normalization is applied (default, backward)

  • axis – [in] Axis over which FFT is performed (default, -1)

  • n – [in] Length of the transformed axis of the output (default, nullopt)
