Seidel adjacency matrix - Wikipedia, the free encyclopedia
In mathematics, in graph theory, the Seidel adjacency matrix of a simple graph G (also called the Seidel matrix and—the original name—the (−1,1,0)- adjacency matrix ) is the symmetric matrix w...

Sci-Tech Dictionary: adjacency matrix ... In mathematics and computer science, an adjacency matrix is a means of representing which vertices of a graph are adjacent to which other vertices. Another matrix representation for a graph is the incidence matrix.

We can associate a matrix with each graph storing some of the information about the graph in that matrix. This matrix can be used to obtain more detailed information about the graph. If a graph has vertices, we may associate an matrix which is called vertex matrix or adjacency matrix.

We make use of the leading eigenvector of the node adjacency matrix. The magnitude order of the co-efficients in this vector defines an edge-connected walk across the graph. We match nodes in different graphs by using their sequence order in the walk.
