Dear developpers,

1)
Does you use this reference to compute Spherical Bessel Functions for 
real argument?

Accurate recursive generation of spherical Bessel and Neumann functions 
for a large range of indices
E. Gillman <http://scitation.aip.org/content/contributor/AU0510272>^1 
and H. R. Fiebig 
<http://scitation.aip.org/search?value1=H.+R.+Fiebig&option1=author&option912=resultCategory&value912=ResearchPublicationContent>Comput. 
Phys. 2, 62(1988); http://dx.doi.org/10.1063/1.168296

2) is there a way to speed up the computation of j_nu(x) if one wants 10 
digits accuracy for instance?

Best regards
