enum dft_pack_format dft

enum class dft_pack_format { … }

Specifies the packing format for real DFT output data. See https://www.kfr.dev/docs/latest/dft_format/ for details

enum constant Perm 

Perm

Packed format: {X[0].r, X[N].r}, ... {X[i].r, X[i].i}, ... {X[N-1].r, X[N-1].i} Number of complex samples is

\(\frac{N}{2}\) where N is the number of real samples

enum constant CCs 

CCs

Conjugate-symmetric format: {X[0].r, 0}, ... {X[i].r, X[i].i}, ... {X[N-1].r, X[N-1].i}, {X[N].r, 0} Number of complex samples is

\(\frac{N}{2}+1\) where N is the number of real samples
