In this paper some properties of a $W$-graph are discussed, and matrix representations of a $W$-graph are given. Future studies and topics on $W$-graphs are introduced.doi:10.1016/0016-0032(92)90002-XHua-An ZhaoJournal of the Franklin Institute
Adjacency Matrix of Graph Create a directed graph using an edge list, and then find the equivalent adjacency matrix representation of the graph. The adjacency matrix is returned as a sparse matrix. s = [1 1 1 2 2 3]; t = [2 3 4 5 6 7]; G = digraph(s,t) ...
Matrix representation of the graph Each cell in the above table/matrix is represented asAij, whereiandjare vertices. The value ofAijis either 1 or 0 depending on whether there is an edge from vertexito vertexj. If there is a path fromitoj, then the value ofAijis 1 otherwise its 0. ...

A character χ corresponding to ρ is the complex-valued function on G defined by χ(g)=tr(ρ(g)) for all g∈G where tr(ρ(g)) is the trace of the matrix representation of ρ(g) on V. A character is said to be irreducible if they are induced from an irreducible representation....
- This is a modal window. No compatible source was found for this media. In practice, there are several alternatives to the adjacency matrix, especially for large and sparse graphs − Adjacency List The adjacency list is a more space-efficient representation for sparse graphs. It uses less ...
Graph Type RepresentationFollowing are the different graph type representations for an incidence matrix −Undirected Graphs: In an undirected graph, each edge is represented by two 1's, one for each of the two vertices connected by the edge. Directed Graphs: In a directed graph, each edge is...
2. This method of representing graphs is not efficient. 3. The time complexity of this algorithm is O(v*v). Problem Solution 1. This algorithm takes the input of the number of vertex. 2. For each pair of vertex ask user whether they are connected or not. ...
