Hi,
I need to compute bessel function for large arguments (for example:
gsl_sf_bessel_Jn(0,20000))
and GSL crashes with the following error message:
gsl: bessel.c:531: ERROR: error
Abort (core dumped)
I check the gsl_sf_bessel_Jn with 2 version of GSL 0.9.4 and 1.1.1:
on GSL 0.9.4, GSL gave me the good value but with the wrong sign and
now with the GSL 1.1.1 it crashes.
Is it a bug or a known limitation of GSL?
