Synopsis#include <flint/gr_dft.h>
void gr_dft_precomp_fprint(FILE * out, const gr_dft_pre_t P)source
void gr_dft_precomp_print(const gr_dft_pre_t P)source

Print a description of the plan to out or to standard output: the algorithm and decomposition of each node, with one indented block per sub-plan, the tables present, and the threading settings if they are not the defaults.

The output is meant for diagnostics and may change. It works for layouts (see _gr_dft_precomp_init_layout) as well as for realised plans. The "root err" figure is the error bound of a fixed-point root table, in units in the last place; over other rings it is a worst-case estimate with no meaning for the actual computation, and it is marked "(est.)" whenever the plan does not store the full table, even if it is exact. gr_dft_precomp_fprint is only declared when stdio.h is included before the FLINT headers.
