A FOTRAN Numerical library (AFNL) is a set of MODULES containing definitions of Fourier series and polynomials, and able to perform linear (multi-)dimensional fittings, resampling (bootstrap) techniques, optimisation, numerical integrals and integration of ODE, sorting/searching data, compute roots of functions, and many other numerical tasks.

The code is all FORTRAN 2003 compilant. Although there are not yet compilers that support the full FORTRAN 2003 standard, recent versions of the intel fortran compiler and gfortran ave the necessary features to compile the library withput any problems.

For years the code has been hosted in sourceforge. Due to the exports restrictions that projects hosted in sourceforge have, and the convienence of using GIT for my projects, I have moved the project to github.

The code is released under the GNU GPL license.
