The NAG Numerical Library is a software product developed and sold by The Numerical Algorithms Group. It is a software library of numerical analysis routines, containing more than 1,700 mathematical and statistical algorithms. Areas covered by the library include linear algebra, optimization, quadrature, the solution of ordinary and partial differential equations, regression analysis, and time series analysis.
Users of the NAG Library call its routines from within their applications in order to incorporate its mathematical or statistical functionality and to solve numerical problems - for example, finding the minimum or maximum of a function, fitting a curve or surface to data, or solving a differential equation. The Library is currently available in the form of the NAG C Library, the NAG Fortran Library, and the NAG Library for .NET, and its contents are accessible from several computing environments, including standard languages such as C, C++, Fortran, Visual Basic, Java and C#, as well as packages such as MATLAB, R, LabVIEW, Excel and Ch. Supported operating systems include the 32 bit and 64 bit versions of Windows, Linux and Mac OS X, as well as Solaris, AIX and HP-UX.

Famous quotes containing the words nag, numerical and/or library:
“... able to
Mend measles, nag noses, blast blisters
And all day waste wordful girls
And war-boys, and all day
Say “Oh God!””
—Gwendolyn Brooks (b. 1917)
“The terrible tabulation of the French statists brings every piece of whim and humor to be reducible also to exact numerical ratios. If one man in twenty thousand, or in thirty thousand, eats shoes, or marries his grandmother, then, in every twenty thousand, or thirty thousand, is found one man who eats shoes, or marries his grandmother.”
—Ralph Waldo Emerson (1803–1882)
“Our civilization has decided ... that determining the guilt or innocence of men is a thing too important to be trusted to trained men.... When it wants a library catalogued, or the solar system discovered, or any trifle of that kind, it uses up its specialists. But when it wishes anything done which is really serious, it collects twelve of the ordinary men standing round. The same thing was done, if I remember right, by the Founder of Christianity.”
—Gilbert Keith Chesterton (1874–1936)
