KokkosFFT::rfftfreq

template<typename ExecutionSpace, typename RealType>
auto KokkosFFT::rfftfreq(const ExecutionSpace&, const std::size_t n, const RealType d = 1.0)

Return the DFT sample frequencies for Real FFTs.

Template Parameters:

• ExecutionSpace – The type of Kokkos execution space

• RealType – The floating point precision type to represent frequencies

Parameters:

• exec_space – [in] Kokkos execution space

• n – [in] Window length

• d – [in] Sample spacing (default, 1)

Returns:

Sampling frequency starting from zero
