摘要：

Let Gamma be a graph with n vertices, where each edge is given an orientation and let Q be the vertex-edge incidence matrix. We obtain a formula for the Moore-Penrose inverse of Q, when Gamma is a distance regular graph. The formula is illustrated by examples. (C) 2018 Elsevier Inc. All rights reserved.
