Numerical Algorithms Group (NAG)


The NAG libraries and supporting software are a large collection of numerical routines ranging from simple implementations of special functions to complex optimization techniques. The libraries include:

  • Fortran Library (original NAG library routines)
  • C-Library
  • fl95 Library
  • SMP and Parallel Libraries (for parallel execution).

The software comes with a Fortran compiler, and a powerful data visualization tool called "Iris Explorer".
