DGLAP equation

This is a library of routines solving the DGLAP evolution equations for parton distribution functions in quantum chromodynamics. The method used here for solving these integro-differential equations is based on an idea by Laurent Schoeffel, explained in the paper "An elegant and fast method to solve QCD evolution equations".
This method uses a decomposition of the parton distribution functions and of the splitting functions into a sum of Laguerre polynomials. The code for computing the coefficients of the Laguerre decomposition of the splitting functions is a mere translation into C of Laurent Schoeffel's original FORTRAN code.
The compressed tar archive containing the library is available at dglap.tar.gz. Note that you need the Gnu Scientific Library in order to compile this code.
