Right.
The initial versions simply used j0() and j1() because these have been
available under Linux for a long time. Then, Eyal wrote jybess(); the
new bessel* functions are simply wrappers for that.
The new versions should appear in the Contrib Archive soon ... I am
having problem downloading the updated octave-ci collection I announced
yesterday. Meanwhile, you can get the whole collection at the URL
ftp://ftp.ci.tuwien.ac.at/pub/export/octave/octave-ci.tar.gz
