Check if a graph is strongly connected

WebNov 3, 2015 · Basically, a matrix representation of a directed graph is fully connected if only the main diagonal contains zeros, because the main diagonal represents the connection of each vertex with itself. Anything different from this represents a not fully connected graph.
