91. Networks And Matrices Networks and matrices. Networks can be represented as graphs or matrices. Forexample, here is a graph Matrix Algebra. matrices are basically tables. http://www.analytictech.com/networks/matrices.htm

Networks and Matrices Networks can be represented as graphs or matrices. For example, here is a graph: We can also record who is connected to whom on a given social relation via what is called an adjacency matrix. The adjacency matrix is a square actor-by-actor matrix like this: And Bil Car Dan Ele Fra Gar Andy Bill Carol Dan Elena Frank Garth If the matrix as a whole is called X, then the contents of any given cell are denoted x ij . For example, in the matrix above, x ij = 1, because Andy likes Bill. Note that this matrix is not quite symmetric (x ij not always equal to x ji Anything we can represent as a graph, we can also represent as a matrix. For example, if it is a valued graph, then the matrix contains the values instead of 0s and 1s. By convention, we normally record the data so that the row person "does it to" the column person. For example, if the relation is "gives advice to", then xij = 1 means that person i gives advice to person j, rather than the other way around. However, if the data not entered that way and we wish it to be so, we can simply transpose the matrix. The transpose of a matrix X is denoted X'. The transpose simply interchanges the rows with the columns. Matrix Algebra Matrices are basically tables. They are ways of storing numbers and other things. Typical matrix has rows and columns. Actually called a 2-way matrix because it has two dimensions. For example, you might have respondents-by-attitudes. Of course, you might collect the same data on the same people at 5 points in time. In that case, you either have 5 different 2-way matrices, or you could think of it as a 3-way matrix, that is respondent-by-attitude-by-time.

SIAM Review Volume 41, Number 2 pp. 335-362 Matrices, Vector Spaces, and Information Retrieval Michael W. Berry, Zlatko Drmac, Elizabeth R. Jessup Abstract. The evolution of digital libraries and the Internet has dramatically transformed the processing, storage, and retrieval of information. Efforts to digitize text, images, video, and audio now consume a substantial portion of both academic and industrial activity. Even when there is no shortage of textual materials on a particular topic, procedures for indexing or extracting the knowledge or conceptual information contained in them can be lacking. Recently developed information retrieval technologies are based on the concept of a vector space. Data are modeled as a matrix, and a user's query of the database is represented as a vector. Relevant documents in the database are then identified via simple vector operations. Orthogonal factorizations of the matrix provide mechanisms for handling uncertainty in the database itself. The purpose of this paper is to show how such fundamental mathematical concepts from linear algebra can be used to manage and index large text collections. Key words.

Faculty of Mathematical Studies University of Southampton Mathematical methods for Physical Sciences Matrices as linear transformations of the plane Matrices can be interpreted as linear transformations of the plane. When you multiply a matrix by a vector you obtain a new vector which, in general, has a different length and a different direction from the original. If we apply a 2x2 matrix to the position vectors of the vertices of a polygon in the xy coordinate plane, we can expect that the polygon will be deformed as the position vectors of its vertices are stretched and rotated. If you click here you can download an Excel spreadsheet (courtesy of Dr Keith Hirst) that will help you understand how matrices can be used to describe linear transformations of figures in the plane.
