adjacency matrix directed graph

What is an undirected edge in an adjacency matrix?
In an adjacency matrix the element at row i column j is 1 if there is an edge from vertex i to vertex j, otherwise it is 0. An undirected edge between i and j lets you travel from i to j and from j to i. So we can represent an undirected edge as two directed edges: one from i to j, and another from j to i.
What is the adjacency matrix of a directed graph?
The adjacency matrix of a directed graph is a logical matrix, and is unique up to permutation of rows and columns. Another matrix representation for a directed graph is its incidence matrix . See direction for more definitions.
What does the adjacency matrix indicate?
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. If the graph is undirected (i.e. all of its edges are bidirectional), the adjacency matrix is symmetric.
What is a binary adjacency matrix?
A binary adjacency matrix whose entries are values of f is defined in such a way that Af is a regular graph whose degree is the Hamming weight of f. The adjacency matrix of a simple labeled graph is the matrix A with A [ [i,j]] or 0 according to whether the vertex vj, is adjacent to the vertex vj or not.
