Block matrix pseudoinverse — is a formula of pseudoinverse of a partitioned matrix. This is useful for decomposing or approximating many algorithms updating parameters in signal processing, which are based on least squares method. Derivation Consider a column wise… … Wikipedia
Block Truncation Coding — Block Truncation Coding, or BTC, is a type of lossy image compression technique for greyscale images. It divides the original images into blocks and then uses a quantiser to reduce the number of grey levels in each block whilst maintaining the… … Wikipedia
Block acknowledgement — Block Acknowledgment = It is a feature in IEEE 802.11 2007 Standard and 802.11n Draft to allow acknowledgement of a group of frames instead of a single frame (as previously used in 802.11a/b).There are mainly two commands to establish a Block… … 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
Block LU decomposition — In linear algebra, a Block LU decomposition is a decomposition of a block matrix into a lower block triangular matrix L and an upper block triangular matrix U . This decomposition is used in numerical analysis to reduce the complexity of the… … Wikipedia
Matrix decomposition — In the mathematical discipline of linear algebra, a matrix decomposition is a factorization of a matrix into some canonical form. There are many different matrix decompositions; each finds use among a particular class of problems. Contents 1… … Wikipedia
Matrix multiplication — In mathematics, matrix multiplication is a binary operation that takes a pair of matrices, and produces another matrix. If A is an n by m matrix and B is an m by p matrix, the result AB of their multiplication is an n by p matrix defined only if… … Wikipedia
Matrix exponential — In mathematics, the matrix exponential is a matrix function on square matrices analogous to the ordinary exponential function. Abstractly, the matrix exponential gives the connection between a matrix Lie algebra and the corresponding Lie group.… … Wikipedia

Block reflector — A block reflector is an orthogonal, symmetric matrix that reverses a subspace whose dimension may be greater than one. * see abstract here http://locus.siam.org/SINUM/volume 25/art 0725014.htmlIt is built out of many elementary reflectors.It is… … Wikipedia
Block Lanczos algorithm for nullspace of a matrix over a finite field — The Block Lanczos algorithm for nullspace of a matrix over a finite field is a procedure for finding the nullspace of a matrix using only multiplication of the matrix by long, thin matrices. These long, thin matrices are considered as vectors of… … Wikipedia
