Synopsis
#include <flint/acb_dft.h>void acb_dft_precomp_init(acb_dft_pre_t pre, slong len, slong prec)sourcevoid acb_dft_precomp_clear(acb_dft_pre_t pre)sourceInitialise a plan for transforms of length len, and free it. The tables of roots of unity and the fixed-point precision are chosen for the working precision prec, so the plan should be built at the precision of the transforms that will use it. For len an empty plan is made, for which the transforms do nothing. Throws an exception if the plan cannot be built.
