incidence matrix with respect to an orientation (Definition)

Let $G$ be a finite graph with $n$ vertices, $\{v_1, \ldots, v_n\}$ and $m$ edges, $\{e_1, \ldots, e_m\}$ For each edge $e = (v_i,v_j)$ of $G$ choose one vertex to be the positive end and the other to be the negative end. In this way, we assign an orientation to $G$ The incidence matrix of $G$ with respect an orientation is an $n \times m$ matrix $D=(d_{ij})$ where
