adjacency matrix example
What is adjacency matrix with example?
In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph.
The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph.
In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal.Adjacency Matrix of a Graph
Two vertices is said to be adjacent or neighbor if it support at least one common edge.
To fill the adjacency matrix, we look at the name of the vertex in row and column.
If those vertices are connected by an edge or more, we count number of edges and put this number as matrix element.
How do you create an adjacency matrix?
How to create an adjacency matrix?
1Identify all of the nodes in the graph.2) Label each node with a unique ID and record the ID of each edge in the network.
3) Calculate the distance between every pair of nodes and store the result in the table of the undirected graph adjacency matrix.
