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?
