X-SW-Source: 2018-q2/txt/msg00000.txt.bz2 Greetings, I have write within the GSL framework, some functions related to the Hurwitz zeta function: first and second derivatives, its logarithm and its logarithmic derivative. These functions are needed to fit properly discrete power law distributions [1]. I think that there is a place for them (along a plfit material) in GSL: what is the procedure to follow ton bring them in GSL ?
