[Maxima] bugs in special functions?

[David Joyner]

Hi:

Based on
http://idlastro.gsfc.nasa.gov/idl_html_help/BESELJ.html
it seems as though the function bessel_j(nu,z) as described
in
http://maxima.sourceforge.net/docs/manual/en/maxima_16.html#SEC52
should be bessel_j(z,nu):

Maxima restarted.
(%i1) bessel_j(2,4.8);

(%o1)                          0.11605038641637
(%i2) bessel_j(4.8,2);

(%o2)                           0.009807521141
(%i3)

There are other Bessel functions which seem to be "backwards" as well.
Does anyone else on this list agree with this?
