A logical matrix, binary matrix, relation matrix, Boolean matrix, or (0,1) matrix is a matrix with entries from the Boolean domain B = {0, 1}. Such a matrix can be used to represent a binary relation between a pair of finite sets. 
The following matrices find their main application in graph and network theory. Adjacency matrix — a square matrix representing a graph, with "aij" non-zero if vertex "i" and vertex "j" are adjacent. Biadjacency matrix — a special class of adjacency matrix that describes adjacency in bipartite graphs. Degree matrix — a diagonal matrix defining the degree of each vertex in a graph. Edmonds matrix — a square matrix of a bipartite graph. Incidence matrix — a matrix representing a relationship between two classes of objects (usually vertices and edges in the context of graph theory). Laplacian matrix — a matrix equal to the degree matrix minus the adjacency matrix for a graph, used to find the number of spanning trees in the graph. Seidel adjacency matrix — a matrix similar to the usual adjacency matrix but with −1 for adjacency; +1 for nonadjacency; 0 on the diagonal. Tutte matrix — a generalisation of the Edmonds matrix for a balanced bipartite graph.

Matrix digital rain, Matrix code or sometimes green rain, is the computer code featured in the "Matrix" series. The falling green code is a way of representing the activity of the virtual reality environment of the Matrix on screen. All three "Matrix" movies, as well as the spin-off "The Animatrix" episodes, open with the code. It is a characteristic mark of the franchise, similar to the opening crawl in "Star Wars".
