Maxima has the variable besselarray. It's no longer documented, but I
think it used to contain the values of the bessel functions since the
computation of a bessel function oftentimes computes the value of the
bessel function for all lower orders.
Bug 1920177
<https://sourceforge.net/tracker/?func=detail&atid=104933&aid=1920177&group_id=4933>;
has several fixes, and the besselarray, besides being currently
broken, also complicates the implementation a bit.
I guess it's important if you're using Fourier-Bessel expansions or
something like that, but perhaps we should provide a different
interface if you want the sequence of values.
Should we keep besselarray around?
