Numerical range — In the mathematical field of linear algebra and convex analysis, the numerical range of a square matrix with complex entries is a subset of the complex plane associated to the matrix. If A is an n × n matrix with complex entries, then… … Wikipedia
Numerical continuation — is a method of computing approximate solutions of a system of parameterized nonlinear equations, The parameter λ is usually a real scalar, and the solution an n vector. For a fixed parameter value λ,, maps Euclidean n space into itself. Often the … Wikipedia
Numerical Recipes — is the generic title of a series of books on algorithms and numerical analysis by William H. Press, Saul Teukolsky, William Vetterling and Brian Flannery. In various editions, the books have been in print since 1986. The most recent edition was… … Wikipedia
Numerical integration — consists of finding numerical approximations for the value S In numerical analysis, numerical integration constitutes a broad family of algorithms for calculating the numerical value of a definite integral, and by extension, the term is also… … Wikipedia
Numerical Wind Tunnel — was an early implementation of the vector parallel architecture developed in a joint project between National Aerospace Laboratory of Japan and Fujitsu. It was the first supercomputer with a sustained performance of close to 100 Gflop/s for a… … Wikipedia
Numerical weather prediction — Weather models use systems of differential equations based on the laws of … Wikipedia
Numerical renormalization group — The Numerical Renormalization Group (NRG) is a technique devised by Kenneth Wilson to solve certain many body problems where quantum impurity physics plays a key role. It is an inherently non perturbative procedure, which was originally used to… … Wikipedia
Numerical analysis — Babylonian clay tablet BC 7289 (c. 1800–1600 BC) with annotations. The approximation of the square root of 2 is four sexagesimal figures, which is about six decimal figures. 1 + 24/60 + 51/602 + 10/603 = 1.41421296...[1] Numerical analysis is the … Wikipedia
Numerical aperture — The numerical aperture with respect to a point P depends on the half angle θ of the maximum cone of light that can enter or exit the lens. In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes… … Wikipedia
