As for this question, you can define $T_X$ and $N_D$ as sheafification of modules in Macaulay2, see Polizzi's answer (and Eisenbud/Sturmfels). Similarily, you can define the map between them, $T_X \to N_D$ and let $T_X(-\log D)$ as the kernel of this map. This gives you a concrete presentation of $F=T_X(-\log D)$ and you can compute $h^2$ using 'HH^2(F)'. | |
