( http://www.matpack.de ) in the source code are references to the numerical algorithms which are used. The author may be contacted via: gammel@matpack.de --------------------------------------------------------------- > BUG#1 -- gsl_sf_hyperg_2F1_e fails for some arguments here one could have a look at the Laguerre Polynomials of matpack, i guess that there is a connection to hyperg_2F1 function. i haven't checked it > BUG#3 -- gsl_sf_bessel_Jn fails for large argument there is a Bessel function , first kind, order n, in matpack also but this I haven't ckecked > BUG#7 -- gsl_sf_coupling_3j loses accuracy for large arguments 3J-symbol in the matpack lib works perfectly is my impression even for very large angular momenta i have ckecked it out ------------------------------------------------------------------ sifac, filip floegel -- +---------------------------------------------------------------+ | dipl.phys.
