WebAdjacency Matrix. An adjacency matrix is one of the most popular ways to represent a graph because it's the easiest one to understand and implement and works reasonably well for many applications. It uses an nxn matrix to represent a graph (n is the number of nodes in a graph). In other words, the number of rows and columns is equal to the ...

Your digraph has an edge from 4 to 3, but not one from 3 to 4. The second column indicates an edge from 3 to 2. You have an edge from 2 to 3. Column 4 is correct; it indicates one of the edges is from 2 to 4 and that edge is indeed included in the digraph. WebMar 25, 2016 · So all the work is done with find and the info: I = incidence (G) returns the sparse incidence matrix for graph G. If s and t are the node IDs of the source and target nodes of the jth edge in G, then I (s,j) = -1 and I (t,j) = 1. That is, each column of I indicates the source and target nodes for a single edge in G. Share. Improve this answer. david c carlson
