Dear All, I have the same problem with partfrac like Albert Reiner had:
kovzol at pascal:~$ maxima
Maxima 5.13.0 http://maxima.sourceforge.net
Using Lisp CLISP 2.38 (2006-01-24)
Distributed under the GNU Public License. See the file COPYING.
Dedicated to the memory of William Schelter.
This is a development version of Maxima. The function bug_report()
provides bug reporting information.
(%i1) load(simplify_sum)$
(%i2) my_partfrac(e, x) := partfrac(num(e)/factor_with_solve(e, x), x)$
(%i3) my_partfrac(1/(x^4+20*x^2+120), x);
Division by 0
#0: my_partfrac(e=1/(x^4+20*x^2+120),x=x)(simplify_sum.mac line 511)
-- an error. To debug this try debugmode(true);
Am I using a too old version of Maxima?
Best regards, Zoltan
