acb_dft_precomp_init, acb_dft_precomp_clear
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 \le 0 an empty plan is made, for which the transforms do nothing. Throws an exception if the plan cannot be built.
