http://planetmath.org/encyclopedia/HermitianMatrix.html

Extractions: Hermitian matrix (Definition) A complex matrix is said to be Hermitian or self-adjoint if where is the transpose , and is the complex conjugate Note that a Hermitian matrix must have real diagonal elements, as the complex conjugate of these elements must be equal to themselves. Any real symmetric matrix is Hermitian; the real symmetric matrices are a subset of the Hermitian matrices. An example of a Hermitian matrix is Hermitian matrices are named after Charles Hermite (1822-1901) [ ], who proved in 1855 that the eigenvalues of these matrices are always real [ H.

5. Newmat Short Introduction
For the manipulation of matrices in the C++ language, oriented towards science and engineering applications.
http://www.robertnz.net/nm_intro.htm

Extractions: This C++ library is intended for scientists and engineers who need to manipulate a variety of types of matrices using standard matrix operations. Emphasis is on the kind of operations needed in statistical calculations such as least squares, linear equation solve and eigenvalues. It supports matrix types: Matrix (rectangular matrix); UpperTriangularMatrix; LowerTriangularMatrix; DiagonalMatrix; SymmetricMatrix; BandMatrix; UpperBandMatrix; LowerBandMatrix; SymmetricBandMatrix; IdentityMatrix; RowVector; ColumnVector. Only one element type (float or double) is supported. The library includes the operations , Kronecker product, Schur product, concatenation, inverse, transpose, conversion between types, submatrix, determinant, Cholesky decomposition, QR triangularisation, singular value decomposition, eigenvalues of a symmetric matrix, sorting, fast Fourier and trig. transforms, printing and an interface with Numerical Recipes in C It is intended for matrices in the range 10 x 10 to the maximum size your machine will accommodate in a single array. The package works for very small matrices but becomes rather inefficient.

http://www.octave.org/doc/octave_19.html

Extractions: Up Top Contents Index There are a number of functions available for checking to see if the elements of a matrix meet some condition, and for rearranging the elements of a matrix. For example, Octave can easily tell you if all the elements of a matrix are finite, or are less than some specified value. Octave can also rotate the elements, extract the upper- or lower-triangular parts, or sort the columns of a matrix. 18.1 Finding Elements and Checking Conditions 18.2 Rearranging Matrices 18.3 Special Utility Matrices 18.4 Famous Matrices ... Index The functions any and all are useful for determining whether any or all of the elements of a matrix satisfy some condition. The find function is also useful in determining which elements of a matrix meet a specified condition. Built-in Function: any x dim For a vector argument, return 1 if any element of the vector is nonzero. For a matrix argument, return a row vector of ones and zeros with each element indicating whether any of the elements of the corresponding column of the matrix are nonzero. For example, any (eye (2, 4)) => [ 1, 1, 0, ]

9. Raven Standard Progressive Matrices
Raven Standard Progressive matrices. Purpose Designed to measure a persons ability to form perceptual relations. Population Ages 6 to adult.
http://www.cps.nova.edu/~cpphelp/RSPM.html

Extractions: Raven Standard Progressive Matrices Purpose: Designed to measure a persons ability to form perceptual relations. Population: Ages 6 to adult. Score: Percentile ranks. Time: (45) minutes. Author: J.C. Raven. Publisher: U.S. Distributor: The Psychological Corporation. Description: The Standard Progressive Matrices (SPM) was designed to measure a persons ability to form perceptual relations and to reason by analogy independent of language and formal schooling, and may be used with persons ranging in age from 6 years to adult. It is the first and most widely used of three instruments known as the Raven's Progressive Matrices, the other two being the Coloured Progressive Matrices (CPM) and the Advanced Progressive Matrices (APM). All three tests are measures of Spearman's g. Scoring: Reliability: Internal consistency studies using either the split-half method corrected for length or KR20 estimates result in values ranging from .60 to .98, with a median of .90. Test-retest correlations range from a low of .46 for an eleven-year interval to a high of .97 for a two-day interval. The median test-retest value is approximately .82. Coefficients close to this median value have been obtained with time intervals of a week to several weeks, with longer intervals associated with smaller values. Raven provided test-retest coefficients for several age groups: .88 (13 yrs. plus), .93 (under 30 yrs.), .88 (30-39 yrs.), .87 (40-49 yrs.), .83 (50 yrs. and over). Validity: Spearman considered the SPM to be the best measure of g. When evaluated by factor analytic methods which were used to define g initially, the SPM comes as close to measuring it as one might expect. The majority of studies which have factor analyzed the SPM along with other cognitive measures in Western cultures report loadings higher than .75 on a general factor. Concurrent validity coefficients between the SPM and the Stanford-Binet and Weschler scales range between .54 and .88, with the majority in the .70s and .80s.

10. FCCR
A working paper on FCCR nxn matrices as local kinematical replacement for CCR, and representations by pxp matrices over Galois fields.
http://graham.main.nc.us/~bhammel/FCCR/fccr.html

Extractions: A working paper on FCCR nxn matricies as local kinematical replacement for CCR, and construction of REPS of CCR by pxp matricies over Galois fields. Some remaining text of the chapters is still being translated to hypertext. An abstract and a brief summary of the essentials are available. The central object of interest here is a chain of algebras given in terms of nxn complex matricies that connect the quantum mechanical Canonical Commutation Relations (CCR) for n unbounded with the Canonical Anticommutation Relations (CAR) for n=2, which seem to provide a local, finite, discrete quantum theory. Finite dimensional representations of CCR by matricies over Galois fields are constructed in appendix J. The detail of mathematics, physics and philosophy presented here is far more than what would be usual in an any professional journal. I believe it to be sufficient that any mathematician/physicist should be able to reproduce and confirm (or correct!) every detail in the exposition.

15. Random Matrices And The Riemann Zeta Function
random matrices and the Riemann zeta function. The GUE consists of all Hermitian N x N matrices, but they are weighted according to the probability density P.
http://www.maths.ex.ac.uk/~mwatkins/zeta/random.htm

Extractions: Conference: "Recent Perspectives in Random Matrix Theory and Number Theory" , Isaac Newton Institute of Mathematical Sciences, Cambridge, UK, 29 March - 8 April 2004 "The connection between random matrix theory and the zeros of the Riemann zeta function was first suggested by Montgomery and Dyson in 1973, and later used in the 1980's to elucidate periodic orbit calculations in the field of quantum chaos. Just in the past few years it has also been employed to suggest brand new ways for predicting the behaviour of the Riemann zeta function and other L -functions. Notwithstanding these successes there has always been the problem that very few researchers are well-versed both in number theory and methods in mathematical physics. The aim of this school is to provide a grounding in both the relevant aspects of number theory, and the techniques of random matrix theory, as well as to inform the students of what progress has been made when these two apparently disparate subjects meet. " This is linked with the Isaac Newton Institute programme: "Random Matrix Approaches in Number Theory" , 26 January - 16 July 2004 "For thirty years there have been conjectured connections, supported by ever mounting evidence, between the zeros of the Riemann zeta function and eigenvalues of random matrices. One of the most famous unsolved problems in mathematics is the Riemann hypothesis, which states that all the non-trivial zeros of the zeta function lie on a vertical line in the complex plane, called the critical line. The connection with random matrix theory is that it is believed that high up on this critical line the local correlations of the zeros of the Riemann zeta function, as well as other
