Recent changes to 28: allow subscripted index e.g. k[1] in sum and producthttp://sourceforge.net/p/maxima/feature-requests/28/2005-06-21T06:00:14Zallow subscripted index e.g. k[1] in sum and product2005-06-21T06:00:14Z2005-06-21T06:00:14ZRobert Dodierhttp://sourceforge.net/u/userid-501686/http://sourceforge.net655e817f49b797b96df2badfa7dc48863ff0958aAt present Maxima requires an index \(as in sum/product\)
to be a symbol. Maxima could relax that to allow
subscripted indices, e.g.
sum \(A\[k\[1\]\], k\[1\], 1, n\);
That could be useful since subscripted indices are
fairly common in math.
I haven't thought about how that could be implemented.
