acb_theta_ctx_tau_struct

acb_theta_ctx_tau_t

The data for summation at a matrix $\tau$ : in particular the matrix exp_tau_div_4 with entries $\exp(\pi i (2 - \delta_{j,k}) \tau_{j,k}/4)$ for $j \le k$ (and its squares, fourth powers and inverses), and for $g > 1$ the Cholesky matrix of $\pi Y$ and $Y^{-1}$ . With allow_shift, additional fields allow the evaluation of $\theta_{a,0}$ for $a \ne 0$ . An acb_theta_ctx_tau_t is an array of length 1.
