Matrix inversion not working. Octave was reinstalled with the same problem.
This however works on various other platforms, (I tested the same version on
open-suse 11.4 and it works- as it should be), for many moons.
History:
Unbuntu 11.04 (desktop) => new install, just a week in operation, all
updates loaded. Problem detected. All default modules was re-installed.
Problem still exist, then all additional octave modules available in
Synaptic Package manager was installed, with the same result.
Problem:
address@hidden:~$ octave
GNU Octave, version 3.2.4
....bla bla bla
Octave was configured for "i686-pc-linux-gnu".
....bla bla bla
octave:1> A=[1,2;3,4];
octave:2> B=inv(A);
panic: Illegal instruction -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Illegal instruction

uname produce the following:
Linux open-suse-ububtu 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12 21:18:14
UTC 2011 i686 athlon i386 GNU/Linux
Stunned,
Any ideas?
Regards
Gerrie
