Gram matrix. In linear algebra, the Gram matrix (or Gramian matrix, Gramian) of a set of vectors in an inner product space is the Hermitian matrix of inner products, whose entries are given by the inner product . [1] If the vectors are the columns of matrix then the Gram matrix is in the general case that the vector coordinates are complex ...
Logical matrix. A logical matrix, binary matrix, relation matrix, Boolean matrix, or (0, 1)-matrix is a matrix with entries from the Boolean domain B = {0, 1}. Such a matrix can be used to represent a binary relation between a pair of finite sets. It is an important tool in combinatorial mathematics and theoretical computer science .
Invertible matrix. In linear algebra, an n -by- n square matrix A is called invertible (also nonsingular, nondegenerate or rarely regular) if there exists an n -by- n square matrix B such that. where In denotes the n -by- n identity matrix and the multiplication used is ordinary matrix multiplication. [1]
These matrices are traceless, Hermitian, and obey the extra trace orthonormality relation, so they can generate unitary matrix group elements of SU(3) through exponentiation. These properties were chosen by Gell-Mann because they then naturally generalize the Pauli matrices for SU(2) to SU(3), which formed the basis for Gell-Mann's quark model.
Formed in 2005, the Newfoundland and Labrador Association of Realtors (NLAR) represents licensed real estate brokers and salespeople in Newfoundland and Labrador . NLAR was formed in 2005 by the amalgamation of the Newfoundland Real Estate Association and three local real estate boards: Central Newfoundland Real Estate Board.
In mathematics, a matrix ( pl.: matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or property of such an object. For example, is a matrix with two rows and three columns. This is often referred to as a "two by three matrix", a " matrix ...
Vandermonde matrix. In linear algebra, a Vandermonde matrix, named after Alexandre-Théophile Vandermonde, is a matrix with the terms of a geometric progression in each row: an matrix. with entries , the jth power of the number , for all zero-based indices and . [1] Some authors define the Vandermonde matrix as the transpose of the above matrix.
