gr_dft_precomp_output_perm
Synopsis
#include <flint/gr_dft.h>void gr_dft_precomp_output_perm(ulong * perm, const gr_dft_pre_t P)sourceWrites to perm (an array of n entries) the permutation by which entry i of the forward output holds X_{\mathit{perm}[i]}; the inverse transform expects X_{\mathit{perm}[i]} in entry i of its input. This is the identity unless the plan has GR_DFT_SCRAMBLED set.
