GraphDistanceMatrix

GraphDistanceMatrix[g]
gives the matrix of distances between vertices for the graph g.

GraphDistanceMatrix[g,d]
gives the matrix of distances between vertices of maximal distance d in the graph g.

Details and OptionsDetails and Options

  • GraphDistanceMatrix returns a SparseArray object or an ordinary matrix.
  • The entries of the distance matrix give the shortest distance from vertex to vertex .
  • The diagonal entries of the distance matrix are always zero.
  • The entry is Infinity () if there is no path from vertex to vertex .
  • In GraphDistanceMatrix[g,d], an entry will be Infinity if there is no path from vertex to vertex in d steps or less.
  • The vertices are assumed to be in the order given by VertexList[g].
  • For a weighted graph, the distance is the minimum of the sum of weights along any path from vertex to vertex .
  • The following options can be given:
  • EdgeWeightAutomaticweight for each edge
    MethodAutomaticmethod to use
  • Possible Method settings include , , and .
