Dear Axiom supporters,
Thank you,
I have installed Axiom from CVS on our RedHat Linux 9 machine.
This makes it
Axiom Version of June 9, 2004.
I find Axiom useful because it has a rich mathematical library.
So far, I have a small question of how to print a polynomial,
polynomial factorization "to line".
The program a.input is of kind
P := MPOLY([p,e,s], Integer)
...
ft = factor f
)spool axres
output ft;
)spool off
The commands > axiom
...
(1) -> )r a.input
yield
---------------------------------------------------------------
-
(s - 1)(s + 1)
*
4 3 2 3
p + (2e + (24s - 4)e)p
+
6 2 4
(e + (60s - 6)e + ... )
+
...
*
p
+
8 2 6 4 2 4
e + (112s - 2)e + (1120s - 120s + 1)e
....
)spool off
>> System error:
Already in dribble (to axres).
------------------------------------------------------------
1. What may be this `error'?
2. I would also like to have the output of kind
" - (s-1) * (s+1) * (p^4 +(2*e^3 + (24*s^2 - 4)*e)*p^3 * ...) * ...
"
For example, my DoCon program can read this format ...
2.1 It prints these polynomials like for (Z[e])[p]:
" (e^2 + 2e)*p "
How to print it like for Z[p,e]:
" 2*p*e + e^2 "
?
Thank you in advance for the help,
