Function ngfft_twiddle_count¶

`function` ngfft_twiddle_count(ngfft_plan<T> &, dft_algorithm) dft ¶

template <typename T>
inline size_t ngfft_twiddle_count(ngfft_plan<T>& plan, dft_algorithm algo = default_dft_algorithm)

Returns the twiddle-factor count for a runtime algorithm value.

Parameters
plan	The plan whose `l2fftsize` selects the specialization.
algo	FFT algorithm (defaults to `fourstep` ).

Returns
	Number of twiddle elements, or `SIZE_MAX` for an invalid FFT size.

Fully qualified name: kfr::ngfft_twiddle_count(ngfft_plan<T> &, dft_algorithm)
