Dear all,
for the solution of a problem I need to use the
hypergeometric function 2F2, in the GSL I founnd other kinds such as 2F1, 2F0
etc.
Is anyone aware of a C implementation of the 2F2 function?
In case I have to provide to the job by myself, it is easy to modify the
series representation, but it seems more difficult to modify the luke or the
reflection. Any suggestions on how to proceed ?
Regards,
Carlo Ferrigno

Unfortunately not.

There is a chapter in Luke, "Special Functions and their approximation
Vol1", on pFq -- that is the only source of information I know about.
