[OctDev] illegal instruction with inv

[Nicolau W. <nwe...@gm...>]

hi folks
perhaps no quite the right list, but I'm using octave 2.1 in debian
sid, and i'm getting the following error whe I try to invert a matrix

octave:1> inv([4 2; 7 6])
panic: Illegal instruction -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Illegal instruction

any ideas? :(

works here on  2.1.42

ans =

Try running ldd on octave. What blas/lapack libraries is it lnked to? I 
have a hunch that it is linking to a P4 version of ATLAS and you have an 
AMD or a P3, that doesn't implement SSE2....
