Rotation Matrix
When discussing a rotation , there are two possible conventions: rotation of the axes and rotation of the object relative to fixed axes. In let a curve be rotated by a clockwise angle so that the original axes of the curve are and and the new axes of the curve are and The matrix transforming the original curve to the rotated curve, referred to the original and axes, is
On the other hand, let the axes with respect to which a curve is measured be rotated by a clockwise angle so that the original axes are and and the new axes are and Then the matrix transforming the coordinates of the curve with respect to and is given by the matrix transpose of the above matrix:

Hadamard Matrix
A Hadamard matrix is a type of square (-1,1)-matrix invented by Sylvester (1867) under the name of anallagmatic pavement, 26 years before Hadamard (1893) considered them. In a Hadamard matrix, placing any two columns or rows side by side gives half the adjacent cells the same sign and half the other sign, with the additional rule that an L -shaped "half-frame" bordering the matrix on two sides and composed entirely of 1s is omitted from the counts. When viewed as pavements, cells with 1s are colored black and those with -1s are colored white. Therefore, the Hadamard matrix must have white squares (-1s) and black squares (1s). A Hadamard matrix of order n is a solution to Hadamard's maximum determinant problem , i.e., has the maximum possible

Matrices Definitie Bewerkingen Eigenschappen Determinanten ... Vergelijkingen Wat is een matrix
Een matrix (meervoud: matrices of matrixen) is in principe een eenvoudig wiskundig begrip, dat baseerd is op een eindige rij getallen, zoals de telrij van 3: 3, 6, 9, ..., 30. Zetten we bij telrijen de getallen naast of onder elkaar, bij matrices doen we beide, Definitie
Een matrix is een rij reële getallen die gerangschikt zijn in rijen en kolommen.
Om aan te geven dat er sprake is van een matrix worden de tekens [ en ] (of soms ook ( en )) gebruikt (zie figuur 1 en 2).
Als m het aantal rijen en n het aantal kolommen is spreekt men van een mxn -matrix of ook van een (m,n)-matrix
Is m n , dan is er sprake van een vierkante matrix. Het aantal rijen (of kolommen) heet dan de orde van de vierkante matrix.
Een kolom van een matrix wordt ook wel kolomvector ; een rij van een matrix heet ook wel rijvector
De (p,q)- en de (m,n)-matrix zijn van hetzelfde type (of van dezelfde vorm ) als p m en q n Hebben we bijvoorbeeld 6 getallen, dan kunnen we deze getallen rangschikken als

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.

The Efficient Computation of Sparse Jacobian Matrices Using Automatic Differentiation
Thomas F. Coleman, Arun Verma
Abstract. This paper is concerned with the efficient computation of sparse Jacobian matrices of nonlinear vector maps using automatic differentiation (AD). Specifically, we propose the use of a graph coloring technique, bicoloring, to exploit the sparsity of the Jacobian matrix J and thereby allow for the efficient determination of J using AD software. We analyze both a direct scheme and a substitution process. We discuss the results of numerical experiments indicating significant practical potential of this approach.

As presented to engineers and as the subject of much numerical analysis, this subject is Matrix Theory. To an algebraist or geometer, it is the theory of Vector Spaces. Linear algebra, sometimes disguised as matrix theory, considers sets and functions which preserve linear structure. In practice this includes a very wide portion of mathematics; thus linear algebra includes axiomatic treatments, computational matters, algebraic structures, and even parts of geometry; moreover, it provides tools used for analyzing differential equations, statistical processes, and even physical phenomena.

    Date: 27 Feb 1995 21:54:27 -0500 From: Steve Toub Subject: Re: Re: A matrix and its inverse Ken- Thank you so much for your help with matrices. I totally understand the multiplication part now, and I understand the idea of an inverse and what it is, but not how to find it. Is there some sort of formula or equation to finding an inverse? The reason that I am asking these questions is that I am in the process of writing a shareware math stack for High School aged kids. The programming part is easy, it is the math that I have a little knowledge problem with. By the way, if I ever get the program done, I will be sure to include your name under the credits.
