Invertible matrix — In linear algebra an n by n (square) matrix A is called invertible (some authors use nonsingular or nondegenerate) if there exists an n by n matrix B such that where In denotes the n by n identity matrix and the multiplication used is ordinary… … Wikipedia
Woodbury matrix identity — In mathematics (specifically linear algebra), the Woodbury matrix identity, named after Max A. Woodbury[1][2] says that the inverse of a rank k correction of some matrix can be computed by doing a rank k correction to the inverse of the original… … Wikipedia
Constraint algorithm — In mechanics, a constraint algorithm is a method for satisfying constraints for bodies that obey Newton s equations of motion. There are three basic approaches to satisfying such constraints: choosing novel unconstrained coordinates ( internal… … Wikipedia
Hat matrix — In statistics, the hat matrix, H, maps the vector of observed values to the vector of fitted values. It describes the influence each observed value has on each fitted value.[1] The diagonal elements of the hat matrix are the leverages, which… … Wikipedia
Transport Layer Security — (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols that provide secure communications on the Internet for such things as web browsing, e mail, Internet faxing, instant messaging and other data transfers. There are… … Wikipedia
Block matrix — In the mathematical discipline of matrix theory, a block matrix or a partitioned matrix is a matrix broken into sections called blocks. Looking at it another way, the matrix is written in terms of smaller matrices.[1] We group the rows and… … Wikipedia
Volker Strassen — is a German mathematician. He received in 2003, with three others, the Paris Kanellakis Award of the ACM, for the Solovay Strassen primality test.In 1971 Strassen published a paper together with Arnold Schönhage on asymptotically fastinteger… … Wikipedia
Fast Kalman filter — The fast Kalman filter (FKF), devised by Antti Lange (1941 ), is an extension of the Helmert Wolf blockingfn|1 (HWB) method from geodesy to real time applications of Kalman filtering (KF) such as satellite imaging of the Earth. Kalman filters are … Wikipedia
Supermatrix — In mathematics and theoretical physics, a supermatrix is a Z2 graded analog of an ordinary matrix. Specifically, a supermatrix is a 2 times;2 block matrix with entries in a superalgebra (or superring). The most important examples are those with… … Wikipedia
Binomial inverse theorem — In mathematics, the binomial inverse theorem is useful for expressing matrix inverses in different ways.If A, U, B, V are matrices of sizes p × p , p × q , q × q , q × p , respectively, then:left(mathbf{A}+mathbf{UBV} ight)^{ 1}=mathbf{A}^{ 1}… … Wikipedia
