NAG Fortran Libraries
NAG has a longstanding worldwide reputation for the excellence of its numerical and statistical procedure libraries. Industry, universities and research institutes rely upon the accuracy, reliability and robustness of these libraries to solve complex problems in areas such as research, engineering, life and earth sciences, and financial analysis. They know that when using the libraries they will save development time and protect their investment in application development.
Support for users wanting to call the NAG Fortran Library from C and C++ is provided by the NAG C Header File described in following documents:
Developing robust, reliable and accurate code for areas covered by the NAG libraries takes many years of effort. Using NAG libraries has regularly been proven to be the most cost effective way of solving numerical and statistical problems, reducing programming time, whilst increasing productivity and confidence.Protects your Investment
You invest much time and money in your application programs. Once they are operational you rely on their results. NAG libraries are regularly updated, fully documented and supported, and designed for portability. Whatever the future holds, you can rely on NAG for your continuing numerical and statistical software needs.
Our libraries provide a broad range of reliable and robust numerical and statistical routines in areas such as optimization, PDEs, ODEs, FFTs, correlation and regression, and multivariate methods, to name but a few. Some people don't want to develop their own application or they need advice on numerical analysis. Here we offer our software development and numeric computation expertise through the Consultancy Service.
Fortran, C and high-performance computing versions of our libraries are available, on a broad and evolving range of platforms, including Windows PC, Unix and Linux.
"You can't criticise the NAG Library - as far as numerical algorithms are concerned it IS the standard."
- Barbara Raw, Program Now - The Advanced Programmers' Journal
Many companies rely on the NAG routines for mission-critical applications, so we operate very stringent quality assurance standards. No procedure enters our libraries until it has been fully tested, validated and verified.
Underpinning the quality of all NAG software is our renowned technical support. To ensure that users' questions are answered to the highest standards customers have access to the actual developers of the software, as well as comprehensive documentation. We place great emphasis on ensuring that our customer support remains at the highest level.
"NAG documentation is so good, its like having a consultant next to you!"
- Mark Haugland of the USA energy leader, Pathfinder
You can be confident that by using the NAG libraries you have access to the most advanced techniques for solving today's complex problems.
