toricIdealPartials(A,D)
A $d \times n$ integer matrix $A$ determines a GKZ hypergeometric system of PDEs in the Weyl algebra $D_n$ over $\mathbb{C}$. The matrix $A$ is associated to the toric ideal $I_A$ in the polynomial subring $\mathbb{C}[\partial_1,...,\partial_n]$ of $D$. A field of characteristic zero may be used instead of $\mathbb{C}$. For more details, see [SST, Chapters 3 and 4].
