21Multitrait-multimethod matrix — The multitrait multimethod (MTMM) matrix is an approach to examining Construct Validity developed by Campbell and Fiske(1959)[1]. There are six major considerations when examining a construct s validity through the MTMM matrix, which are as… …
22Square root of a matrix — In mathematics, the square root of a matrix extends the notion of square root from numbers to matrices. A matrix B is said to be a square root of A if the matrix product B · B is equal to A.[1] Contents 1 Properties 2 Computation methods …
23Random matrix — In probability theory and mathematical physics, a random matrix is a matrix valued random variable. Many important properties of physical systems can be represented mathematically as matrix problems. For example, the thermal conductivity of a… …
24Belief decision matrix — Similar to decision matrix, a belief decision matrix is used to describe a multiple criteria decision analysis (MCDA) problem in the Evidential Reasoning Approach. If in an MCDA problem, there are M alternative options and each need to be… …
25Dependency Structure Matrix — A Dependency Structure Matrix, or DSM (also referred to as Dependency Structure Method, Design Structure Matrix, Problem Solving Matrix (PSM), incidence matrix, N square matrix or Design Precedence Matrix), is a compact, matrix representation of… …
26Boston Consulting Group's Advantage Matrix — After its well known ‘growth share matrix the Boston Consulting Group subsequently developed another, much less widely reported, matrix which approached the economies of scale decision rather more directly. This is their Advantage Matrix… …
27Hasse–Witt matrix — In mathematics, the Hasse–Witt matrix H of a non singular algebraic curve C over a finite field F is the matrix of the Frobenius mapping (p th power mapping where F has q elements, q a power of the prime number p) with respect to a basis for the… …
28The Matrix — For the series, see The Matrix (franchise). For other uses, see Matrix. The Matrix Theatrical release poster Directed by Andy Wachowski Larry Wachowski …
29Orthogonal matrix — In linear algebra, an orthogonal matrix (less commonly called orthonormal matrix[1]), is a square matrix with real entries whose columns and rows are orthogonal unit vectors (i.e., orthonormal vectors). Equivalently, a matrix Q is orthogonal if… …
30Sparse matrix — A sparse matrix obtained when solving a finite element problem in two dimensions. The non zero elements are shown in black. In the subfield of numerical analysis, a sparse matrix is a matrix populated primarily with zeros (Stoer Bulirsch 2002,… …
