Kurt Hornik's current collection of functions for Octave includes a
newer version of besslj() that uses jybess() instead of j0() or j1().
You can get Kurt's files from ftp.ci.tuwien.ac.at in the directory
/pub/export/octave.  I believe jybess() is available from the archive
of contributed functions at www.tsc.uvigo.es.
