In fact, my second idea was to interpolate intevals [a,b] (which should
contain zero) for a given Jn, and then for Jn
for all n. Both should be linear interpolation.
But I can't get it working fine because linear interpolation does not
match very well [a,b] values :-(
So... I don't know.
Nevertheless, I have at least one solution to find out zeros of
spherical Bessel, which works fine.
Thanks to all.
Cheers,
