Synopsis
#include <flint/acb_dirichlet.h>void acb_dirichlet_hardy_z(acb_ptr res, const acb_t t, const dirichlet_group_t G, const dirichlet_char_t chi, slong len, slong prec)sourceSets res to the first len Taylor coefficients of , computed as with acb_dirichlet_l_jet. For the Riemann zeta function, this uses the Riemann–Siegel formula when is large and len . If is real, the imaginary parts are set to exactly zero.
