void acb_dirichlet_platt_ws_interpolation(arb_t res, arf_t deriv, const arb_t t0, arb_srcptr p, const fmpz_t T, slong A, slong B, slong Ns_max, const arb_t H, slong sigma, slong prec)source

Sets res to acb_dirichlet_platt_scaled_lambda at t_0, by Gaussian-windowed Whittaker–Shannon interpolation of the grid values p. If deriv is not NULL, it is set to an approximation of the derivative. Ns_max is the maximum number of grid points used on either side of t_0, H is the standard deviation of the Gaussian window, and sigma is an odd positive integer used in the error bounds.
