NAG Numerical Libraries

NAG Numerical Libraries is a software product sold by The Numerical Algorithms Group Ltd (a non-profit company). The product is a software library of numerical analysis routines. It comprises a collection of 1500 mathematical and statistical algorithms. Areas covered include linear algebra, optimization, quadrature, differential equations, regression analysis, and time series analysis. The code has been contributed by many people.

The software cannot be used stand-alone and must be embeded into other software applications. NAG is currently available in Fortran and the C (gcc) programming languages. Supported operating systems include Windows, Linux (including 64-bit), Solaris, Mac OS X, AIX, HP-UX, IRIX and Tru64.

The routines normally use hardware arithmetic. Arbitrary-precision arithmetic can be used instead, for routines called within Maple.
