View Full Version : [ubuntu] Octave: matrix inversion fatal error

October 8th, 2011, 08:12 PM
Matrix inversion not working. Octave was reinstalled with the same problem. This however works on various other platforms, (I tested the same octave version on open-suse 11.4 and it works- as it should be, for many moons)

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.

gerrie@open-suse-ubuntu:~$ octave
GNU Octave, version 3.2.4
....bla bla bla
Octave was configured for "i686-pc-linux-gnu".

octave:1> A=[1,2;3,4];
octave:2> B=inv(A);

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

Any ideas?
