An adjacency matrix allows representing a graph with a V × V matrix M = [f(i, j)] where each element f(i, j) contains the attributes of the edge (i, j). In an adjacency matrix, there is a 1 at position (i, j) if there is an edge from vertex i to vertex j.Therefore, all the outgoing edges of vertex i are in row i.A sum of row i therefore gives you the outdegree of vertex i.. For a transposed adjacency matrix, sum along the columns. And this is using matrix multiplication. 2. An 'x' means that that vertex does not exist (deleted).
