 Adjacency matrices are often square and both out-vertices (rows) and the in-vertices (columns) are the same set of vertices.

  A B C
 D 1 0 0
 F 0 0 0
 G 0 0 1

 The above matrix represents two 6 vertices and two edges. They could be represented as:

 D -> A
 G -> C

 With a weighted adjacency matrix you could use values other than 1. For example,

     A  B  C
 D 0.25  0  0
 F    0  0  0
 G    0  0  0.76
