Detailed Description

template<typename T, int_t N, int S, int_t K>
struct GFFT::ComputeTwiddles< T, N, S, K >

Template Parameters

T	value type
N	length of the data
S	sign of the transform (-1 for inverse)

Computes twiddle factors, e.g. cos(2*pi/N),...,cos(2*K*pi/N) and sin(2*pi/N),...,sin(2*K*pi/N). It is used for prime factors greater than 3.
