21Random matrix — In probability theory and mathematical physics, a random matrix is a matrix valued random variable. Many important properties of physical systems can be represented mathematically as matrix problems. For example, the thermal conductivity of a… …
22Eigendecomposition of a matrix — In the mathematical discipline of linear algebra, eigendecomposition or sometimes spectral decomposition is the factorization of a matrix into a canonical form, whereby the matrix is represented in terms of its eigenvalues and… …
23RF Switch Matrix — or Microwave Switch Matrix or Switch Matrix An RF/Microwave Switch Matrix is used in test systems, in both design verification and manufacturing test, to route high frequency signals between the device under test (DUT) and the test and… …
24Nuclear matrix — In biology, the nuclear matrix is the network of fibres found throughout the inside of a cell nucleus and is somewhat analogous to the cell cytoskeleton. However, in contrast to the cytoskeleton, the nuclear matrix has been proposed to be a… …
25Cartilage oligomeric matrix protein — Cartilage oligomeric matrix protein, also known as COMP, is a human gene.cite web | title = Entrez Gene: COMP cartilage oligomeric matrix protein| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene Cmd=ShowDetailView TermToSearch=1311|… …
26Shift matrix — In mathematics, a shift matrix is a binary matrix with ones only on the superdiagonal or subdiagonal, and zeroes elsewhere. A shift matrix U with ones on the superdiagonal is an upper shift matrix.The alternative subdiagonal matrix L is… …
27Seidel adjacency matrix — In mathematics, in graph theory, the Seidel adjacency matrix of a simple graph G (also called the Seidel matrix and the original name the (−1,1,0) adjacency matrix) is the symmetric matrix with a row and column for each vertex, having 0 on the… …
28Spread of a matrix — In matrix theory, the spread of a matrix describes how far apart the eigenvalues are in the complex plane. Suppose A is a square matrix with eigenvalues lambda 1, ldots, lambda n. Then the spread of A is the non negative number:s(A) = max… …
29Density matrix renormalization group — The density matrix renormalization group (DMRG) is a numerical variational technique devised to obtain the low energy physics of quantum many body systems with high accuracy. It was invented in 1992 by Steven R. White and it is nowadays the most… …
30Folded Spectrum Method — (FSM) ist ein mathematisches iteratives Optimierungsverfahren für Eigenwertprobleme. Mit ihm ist es möglich, den Eigenvektor Ψ eines großen Eigenwertproblems zur Matrix H zu bestimmen, der am nächsten an einem beliebigen Ziel Eigenwert ε liegt,… …
