What is NAG Library?
The NAG Library is a collection of implementation of numerical and statistical algorithms developed by the Numerical Algorithms Group (NAG). It is available on different operating systems supporting various programming languages and software packages including C, C++,C#, Fortran, Java, MATLAB, Excel, .NET, R, etc.
Major Library contents:
- Optimization – local and global optimization solvers
- Ordinary and partial differential equations
- Mesh generation
- Wavelet transforms
- Option pricing
- Numerical integration
- Roots of nonlinear equations (including polynomials)
- Dense, banded and sparse linear equations and eigenvalue problems
- Linear and nonlinear least squares problems
- Special functions
- Curve and surface fitting and interpolation
- Random number generation
- Simple calculations of statistical data
- Correlation and regression analysis
- Multivariate methods
- Analysis of variance and contingency table analysis
- Time series analysis
- Nonparametric statistics

Using NAG Library
(1) Chi Wah Learning Commons and PC classrooms
NAG C Library, NAG Fortran Library, NAG Library for .NET and NAG Fortran Compiler (Windows version) are installed on the Chi Wah Learning Commons and LES classrooms (CPD-3.41).
(2) HKU staff and students personal computer
HKU staff and students can also obtain the PC version (for Windows, Linux and Mac OS) of the Library and install on your PC within the HKU campus. Departmental technician may also install NAG Library in departmental laboratory’s PCs. Please contact Miss Lilian Chan, HPC Team if you want to get the NAG products.
For any technical issue on software installation and application example, you may also contact NAG directly via support@nag.co.uk.
