    Extractions: Example: Non verbal test - Raven's Progressive Matrices The Raven Progressive Matrices test is a widely used intelligence test in many research and applied settings. In each test item, one is asked to find the missing pattern in a series. Each set of items gets progressively harder, requiring greater cognitive capacity to encode and analyze. Sample item from the Raven Progressive Matrices tests Raven's Progressive Matrices was designed primarily as a measure of Spearman's g. There are no time limits and simple oral instructions. There are 3 different tests for different abilities: In terms of its psychometrics, Raven's Progressive Matrices: has good test-retest reliability between .70 and .90 (however, for low score ranges, the test-retest reliability is lower) has good internal consistency coefficients - mostly in the .80s and .90s

    Extractions: Texas Instruments Calculators Casio Calculators Sharp Calculators Hewlett Packard Calculators ... Contact Webmaster Balancing Equations Using Matrices NOTE: this application requires that you have a calculator capable of doing MATRICES. Most if not all graphical calculators have this capability. This reading uses the Texas Instrument TI-82 Graphical Calculator as an example. Early on in your chemistry studies, you will have ample opportunity to balance equations! This is a fundamental skill in chemistry, as you might have noticed from the short reading in stoichiometry! Balancing equations means writing chemical equations such that the amount of stuff you start with in the reaction equals the amount of stuff you end up with as a product. In other words, if I start baking bread with 10 pounds of flour, I should end up with 10 pounds of bread, unless some is lost onto the floor or if some of it goes up in smoke! A simple example goes a long way. We can form water by combing hydrogen gas (H

    http://www.vacuumdistillation.biz
    
    Extractions: The Vacuum Distillation Technique was developed by the US EPA specifically to overcome matrix effects from a wide range of sample matrices. This new Vacuum Distillation technique addresses most of the deficiencies that have long plagued the existing VOC techniques. Unlike and Head Space techniques, Vacuum Distillation has a theoretical basis. The analyte recoveries using Vacuum Distillation are based on the boiling points and partition coefficients of analytes being extracted. Vacuum Distillation simpler and more reliable Each and every sample test has built in quality control features that provide a level of confidence not available by Purge and Trap or Head Space techniques.

Open your computer algbera system now by clicking its icon in the navigation frame. We are often interested in data that is most naturally written as a matrix or array For example, in chapter 1 we used matrices to represent images. Matrices are also discussed in the section on matrices in the mathematical infrastructure. In that section we discuss adding two matrices and multiplying a matrix by a real number. Vectors can be thought of as matrices Vectors are often thought of as either a matrix with one row or as a matrix with one column. We call a vector a row vector when we think of it as a matrix with one row and a column vector when we think of it as a matrix with one column. The transpose of a matrix It is sometimes useful to exchange the roles of the rows and columns. For example, consider the two matrices written below. The lefthand matrix describes the traffic flow each morning as commuters drive from their homes in three towns Oak, Elm, and Maple to their jobs at three companies ABC Co., DEF Co., and GHI Co. The table on the right shows the traffic each afternoon as commuters return home. Notice that the rows of the first matrix become the columns of the second matrix. This matrix is called the transpose of the first matrix.

88. Newmat Short Introduction

    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.

Print-friendly page Adding and Subtracting Matrices Matrix addition is fairly simple, and is done entry-wise. Up until now, you've been able to add any two things you felt like: numbers, variables, equations, and so forth. But addition doesn't always work with matrices. Perform the indicated operation, or explain why it is not possible. Since matrices are added entry-wise, I have to add the and the , the and , the and the , and the and the . But what do I add to the and to the ? There are no corresponding entries in the first matrix that can be added to these entries in the second matrix. So the answer is: I can't add these matrices, because they're not the same size

    Classification of Hadamard matrices and designs.  
    http://www.maths.gla.ac.uk/~es/
    
    Extractions: My research interests at the present time are in the area of classification of combinatorial designs of various different sorts. In some cases I have been able to classify the designs completely and where this has been possible I have stored the designs on disc. They can be accessed via the Table below. These files will be updated at intervals, as I find the time. Recently, along with Andries Brouwer, I have extended some of the results that Willem Haemers and I obtained concerning cospectral graphs, W. H. Haemers, E. Spence Enumeration of cospectral graphs, European J. Combin, 25 (2004), 199-211. In that paper Haemers and I considered graphs with n vertices and determined the number that were cospectral with respect to the usual graph spectrum, together with the number cospectral with respect the Laplace and unsigned Laplace spectrum. Moreover, we also found the number of graphs G, H for which both G and H are cospectral and also their complements. For details of the results for the usual spectrum and n see Andries Brouwer's home page or files on this computer . So far I have completed the investigation for n = 12 and the signless Laplace spectrum . The results are listed here . The results for the Laplace spectrum can be found here One further aspect considered in the above paper is the question of the number of graphs G for which G and its complement G' have the same pair of characteristic polynomials, (

    Extractions: by Steve Borgatti, Boston College Overview The typical dataset collected by a sociologist and certain kinds of anthropologists can be formatted as a matrix (see figure) in which the rows correspond to respondents and the columns correspond to variables. For example: This kind of matrix is called "2-way" because it is 2-dimensional: it has both rows and columns. A one-way matrix is just a single list of numbers it would ordinarily be called an array or a vector. Some matrices are 3-way, because they have rows, columns and levels. For example, if we ask ten respondents to rate 3 brands of computer on 5 attributes, the result would be a 3-way matrix, which we can think of as a 3-dimensional object, like a cube (see figure). Alternatively, we can think of the data as forming a collection of 2-way matrices, each of which is a slice from the cube. For example, we might consider the data to consist of five respondent-by-brand matrices, one for each attribute. These correspond to vertical slices of the cube. Another way to think of it is that each respondent is rating each brand on every attribute, so there is a brand-by-attribute matrix for each respondent. This corresponds to taking horizontal slices through the cube. If we then collected the same data on the same respondents at different points in time, we could record the whole thing in a 4-way matrix, which we can think of as a collection of cubes, one for each time period.

94. The Hadamard Maximal Determinant Problem
    List of known {-1,1}-matrices with largest determinant and D-optimal designs.  
    http://www.indiana.edu/~maxdet
    
    Extractions: The Hadamard maximal determinant problem asks when a matrix of a given order with entries -1 and +1 has the largest possible determinant. Despite well over a century of work by mathematicians, beginning with Sylvester's investigations of 1867, the question remains unanswered in general. The table lists current record determinants. Clicking on a determinant will display a maximal matrix or matrices and other relevant information including references to the literature. Det should be multiplied by 2 N-1 . Refer to key for more information. N Det R N Det R N Det R N Det R The aim of this page is to inspire people to try to improve the above numbers (where possible). If you are aware of better bounds or other constructions, please notify the authors of this page (email: maxdet at indiana dot edu). Likewise, if you feel your work, or somebody else's, is not properly credited, we want to hear from you! A related (and even more difficult) problem is the determinant spectrum problem which asks, not just for the maximal determinant, but for the complete set of values taken by the determinant function.

    http://www.math.rwth-aachen.de/~Ines.Hoehler/
    
    Extractions: Collapsed Adjacency Matrices, Character Tables and Ramanujan Graphs This is a database of character tables of endomorphism rings. Let G be a finite group, K a field and M a finite set on which G acts transitively. For a in M let M ,...,M r be the distinct orbits of G a , which have respective representatives a =a, a ,..., a r . Let E i i [k,l] be the collapsed adjacency matrix for the orbital digraph (M,E i ). Therefore A i is defined as the number of neighbours of a k in M l (see PrSoi for details). (see CePoTeTrVe for details). For rank up to 5 the collapsed adjacency matrices have been computed by Cheryl E. Praeger and Leonard H. Soicher (PrSoi) . Several matrices (also for larger rank cases) can be found in IvLiLuSaSoi , where numerous further references are given.) The following matrices originally have been published in:
