Permutation matrix — In mathematics, in matrix theory, a permutation matrix is a square (0,1) matrix that has exactly one entry 1 in each row and each column and 0 s elsewhere. Each such matrix represents a specific permutation of m elements and, when used to… … Wikipedia
Permutation box — In cryptography, a permutation box (or P box) is a method of bit shuffling used to permute or transpose bits across S boxes inputs, retaining diffusion while transposing.[1] In block ciphers, the S boxes and P Boxes are used to make the relation… … Wikipedia
Orientation (vector space) — See also: orientation (geometry) The left handed orientation is shown on the left, and the right handed on the right. In mathematics, orientation is a notion that in two dimensions allows one to say when a cycle goes around clockwise or… … Wikipedia
Parker vector — In mathematics, especially the field of group theory, the Parker vector is an integer vector that describes a permutation group in terms of the cycle structure of its elements.DefinitionThe Parker vector P of a permutation group G acting on a set … Wikipedia
Schreier vector — In mathematics, especially the field of computational group theory, a Schreier vector is a tool for reducing the time and space complexity required to calculate orbits of a permutation group.OverviewSuppose G is a finite group with generating… … Wikipedia
Interval vector — In musical set theory, an interval vector (also called an interval class vector or ic vector) is an array that expresses the intervallic content of a pitch class set.In 12 equal temperament it has six digits, with each digit standing for the… … Wikipedia
Determinant — This article is about determinants in mathematics. For determinants in epidemiology, see Risk factor. In linear algebra, the determinant is a value associated with a square matrix. It can be computed from the entries of the matrix by a specific… … Wikipedia
Orthogonal 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… … Wikipedia
