Struct Cmplx

Namespace

NumSharp.Fourier

Assembly

NumSharp.dll

Port of pocketfft's cmplx<T0> for the double engine (T0 == double). The field layout (r then i) is identical to Complex (real then imaginary), so the two are bit-reinterpretable at the driver boundary. All operators reproduce pocketfft's exact real/imag operation order.
