WebAn adjacency list is a hybrid between an adjacency matrix and an edge list that serves as the most common representation of a graph, due to its ability to easily reference a vertex 's neighbors through a linked list. Through the use of adjacency list, it is easy to look up a node's neighbors in constant or O (1) time. WebFind the adjacency matrix of the graph. A = adjacency (G) A = (1,2) 1 (3,2) 1 (1,3) 1 (4,3) 1 (1,4) 1 (2,4) 1 This form of the adjacency matrix does not include the edge weights. Use the 'weighted' option to include the edge weights in the adjacency matrix. A = adjacency (G, 'weighted') A = (1,2) 5 (3,2) 9 (1,3) 6 (4,3) 10 (1,4) 7 (2,4) 8 WebA = adjacency (G,'weighted') returns a weighted adjacency matrix, where for each edge (i,j), the value A (i,j) contains the weight of the edge.
