I replace the library lapack-3.0-25 for lapack-3.0-14. I copy from a redhat 7.3 /usr/lib/lapack* to my directory. !!! And the lsim function in octave runs fine. !!! So i think that lapack-3.0.25 dont work fine.
This is lapack problem. This problem is fixed in the latest fc3 lapack version (lapack-3.0-26.fc3). Ivana Varekova
