Description
We present a method to unfold the complete functional dependence of single-scale quantities as
QCD splitting functions and Wilson coefficients from a finite number of moments. These quantities
obey recursion relations which can be found in an automated way. The exact functional form is obtained
solving the corresponding difference equations. We apply the algorithm to the QCD Wilson coefficients for deep-inelastic scattering and splitting functions to 3-loop order which are associated with difference
equations of rather high order and degree.
