WebJun 26, 2024 · DG.EdgeCData = CDataVec; c = colorbar; My understanding is that adjacency matrices map onto digraphs such that the row ID is directed to the column ID (eg data in row 4, column 1 of adjacency matrix 'A' would have node 4 connecting to node 1 in the digraph). The edge color I would like in this case is 0.3 (since that is the value at row … WebMar 29, 2024 · Adjacency Matrix is a 2D array of size V x V where V is the number of vertices in a graph. Let the 2D array be adj [] [], a slot adj [i] [j] = 1 indicates that there is an edge from vertex i to vertex j. Adjacency matrix for undirected graph is always symmetric. Adjacency Matrix is also used to represent weighted graphs. palini e bertoli san giorgio di nogaro
