Earliest Uses of Symbols for Matrices and Vectors This page has been contributed by John Aldrich of the University of Southampton. Last revision: April 13, 2007. For matrix and vector entries on the Words pages, see here for a list. For vector analysis words see here ; vector analysis symbols are on the calculus page Most of the basic notation for matrices and vectors in use today was available by the early 20 th century. Its development is traced in volume 2 of History of Mathematical Notations published in 1929. Cajori made much use of 4-volume The Theory of Determinants in the Historical Order of Development (1906-24) which covered the years 1990-1900; a supplement (1930) brought the story up to 1920. The modern reader of Muir will be struck that he invested so much in a history of determinants but determinants seemed so much more central at the end of the 19 th century when Muir began work than they do now. The modern reader of Cajori will be struck by how very differently The emphasis on matrices and the blending of matrix algebra and abstract linear spaces only became features of undergraduate mathematics after the Second World War. See the entry LINEAR ALGEBRA on Words.

64. Matrices And Other Arrays In LaTeX matrices and other arrays are produced in LaTeX using the \textbf{array} environment. For example, suppose that we wish to typeset the following passage http://www.maths.tcd.ie/~dwilkins/LaTeXPrimer/Matrices.html

Matrices and other arrays in LaTeX This passage is produced by the following input: First of all, note the use of and to produce the large delimiters around the arrays. As we have already seen, if we use then the size of the parentheses is chosen to match the subformula that they enclose. Next note the use of the alignment tab character to separate the entries of the matrix and the use of to separate the rows of the matrix, exactly as in the construction of multiline formulae described above. We begin the array with and end it with . The only thing left to explain, therefore, is the mysterious which occurs immediately after . Now each of the c 's in represents a column of the matrix and indicates that the entries of the column should be centred. If the c were replaced by l then the corresponding column would be typeset with all the entries left-justified, and r would produce a column with all entries right-justified. Thus produces We can use the array environment to produce formulae such as Note that both columns of this array are set flush left. Thus we use immediately after . The large brace is produced using . However this requires a corresponding discussed earlier. This delimiter is invisible. We can therefore obtain the above formula by typing

Sites for parents Matrices Help Relationships William A. McWorter Jr. Once when I was a graduate student I had a conversation with a philosophy professor friend about epistomology. He said there is a problem with the referent theory of meaning. The planet Venus and the Morning Star have the same referent, the planet, but the phrases clearly have different meanings. Being a student of mathematics, I had recently learned that mathematicians treat relationships as objects like any other object. So I suggested "why not include relationships as referents?". Then the Morning Star would have as one of its referents the relationship between Venus and the morning, distinguishing that phrase from the planet Venus. The philospher said "then the universe would have too many objects". Not long after that I gave up on philosophy. It seemed to me that philosphers were not interested in the truth. They prefer to haggle endlessly over dilemmas. This same relationship can be recorded as a matrix. Label the rows and columns of matrix by E, J, and P. Place a 1 in a cell of the matrix provided the row label of the cell is related to the column label of that cell. Put zeros in all other cells of the matrix.

Not Positive Definite MatricesCauses and Cures The seminal work on dealing with not positive definite matrices is Wothke (1993) . The chapter is both reabable and comprehensive. This page uses ideas from Wothke, from SEMNET messages, and from my own experience. The Problem There are four situations in which a researcher may get a message about a matrix being "not positive definite." The four situations can be very different in terms of their causes and cures. First, the researcher may get a message saying that the input covariance or correlation matrix being analyzed is "not positive definite." Generalized least squares (GLS) estimation requires that the covariance or correlation matrix analyzed must be positive definite, and maximum likelihood (ML) estimation will also perform poorly in such situations. If the matrix to be analyzed is found to be not positive definite, many programs will simply issue an error message and quit. Second, the message may refer to the asymptotic covariance matrix. This is not the covariance matrix being analyzed, but rather a weight matrix to be used with asymptotically distribution-free / weighted least squares (ADF/WLS) estimation.

Nucleotide Count Matrices for a Selection of Cis-elements Each matrix contains counts of adenines, cytosines, guanines, and thymines observed at each position in a sample of cis-elements of one type. With current data, it is not possible to construct accurate matrices for each of the thousands of human transcription factors, or the tens of thousands of dimers. Fortunately, transcription factors naturally belong to families that posssess similar, though generally not identical, DNA binding properties. These matrices therefore represent approximate DNA binding representations for selected families of transcription factors. This list will grow in the future, and it will be necessary to accommodate factors that bind to motifs of varying length or half-site organization.

Hermitian Matrices Given a matrix A of dimension m k (where m denotes the number of rows and k denotes the number of columns) and a matrix B of dimension k n, the matrix product AB is defined as the m n matrix with the components for m ranging from 1 to m and for n ranging from 1 to n. Notice that matrix multiplication is not generally commutative, i.e., the product AB is not generally equal to the product BA. The transpose A T of the matrix A is defined as the k m matrix with the components for m ranging from 1 to m and for k ranging from 1 to k. Notice that transposition is distributive, i.e., we have (A+B) T = (A T + B T Combining the preceding definitions, the transpose of the matrix product AB has the components Hence we've shown that We can also define the complex conjugate A of the matrix A as the m k matrix with the components Notice that the matrix A can be written as the sum A R + iA I where A R and A I are real valued matrices. The complex conjugate of A can then be written in the form We also note that transposition and complex conjugation are commutative, i.e., we have (A T = (A T . Hence the composition of these two operations (in either order) gives the same result, called the

Housing Contact Home Invited Participants ... Thematic Year The mathematics that has been developed for Random Matrix Theory in the past two decades is astonishingly rich and includes variational techniques, inverse spectral approach to nonlinear integrable differential and difference systems, new asymptotic techniques, such as the nonlinear steepest descent method, free probability and large deviations methods. The results obtained have found new applications in a stunningly wide range of areas of both mathematics and theoretical physics such as, for example, approximation theory, orthogonal polynomials and their asymptotics, number theory, combinatorics, dynamical systems of integrable type, representation theory of finite and infinite groups, growth phenomena, quantum gravity, conformal field theory, supersymmetric Yang-Mills theory and string theory. This workshop will focus on recent advances in the asymptotic spectral theory of random matrices, connections with (multi-)orthogonal polynomials, combinatorics and moduli space theory of Riemann surfaces, algebraic geometry, theory of isomonodromic deformations, number theory and Dyson processes.
