21Rotation matrix — In linear algebra, a rotation matrix is a matrix that is used to perform a rotation in Euclidean space. For example the matrix rotates points in the xy Cartesian plane counterclockwise through an angle θ about the origin of the Cartesian… …
22Cross product — This article is about the cross product of two vectors in three dimensional Euclidean space. For other uses, see Cross product (disambiguation). In mathematics, the cross product, vector product, or Gibbs vector product is a binary operation on… …
23Pfaffian — In mathematics, the determinant of a skew symmetric matrix can always be written as the square of a polynomial in the matrix entries. This polynomial is called the Pfaffian of the matrix. The Pfaffian is nonvanishing only for 2 n times; 2 n skew… …
24AA tree — In computer science, AA trees (Arne Andersson trees) are a form of balanced trees used for storing and retrieving ordereddata efficiently.Unlike red black trees, red nodes on an AA tree can only be added as a right subchild. In other words, no… …
25Copper cable certification — 10G Certification Kit In copper twisted pair wire networks, copper cable certification is achieved through a thorough series of tests in accordance with Telecommunications Industry Association (TIA) or International Organization for… …
26Árbol AA — En informática un árbol AA es un tipo de árbol binario de búsqueda auto balanceable utilizado para almacenar y recuperar información ordenada de manera eficiente. Los árboles AA reciben el nombre de su inventor, Arne Andersson. Los árboles AA son …
27Cayley transform — In mathematics, the Cayley transform, named after Arthur Cayley, has a cluster of related meanings. As originally described by Harvtxt|Cayley|1846, the Cayley transform is a mapping between skew symmetric matrices and special orthogonal matrices …
28Orthogonal 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… …
29Bilinear form — In mathematics, a bilinear form on a vector space V is a bilinear mapping V × V → F , where F is the field of scalars. That is, a bilinear form is a function B : V × V → F which is linear in each argument separately::egin{array}{l} ext{1. }B(u + …
