VertexIndex

VertexIndex[g, v]
gives the integer index for the vertex v in the graph g.

Details Details

VertexIndex gives the ordering used in functions such as VertexList, AdjacencyMatrix, KirchhoffMatrix, IncidenceMatrix, and GraphDistanceMatrix.
VertexIndex[g, v] gives the position for a vertex v in VertexList[g].
VertexIndex[g, v] gives the row position for a vertex v in IncidenceMatrix[g].
VertexIndex[g, v] gives the row and column position for a vertex v in AdjacencyMatrix[g], KirchhoffMatrix[g], and GraphDistanceMatrix[g].

Find the integer index of a vertex:

Out[1]=

Out[2]=

The index corresponds to the position in the vertex list:

Out[3]=
