From discussions with package's author, it appears that using either atlas or Accelerate for lapack leads to numerical problems. We therefore also can use the reference lapack implementation from Fink's lapack342 package. Install control-ref-oct360 to use it. To see the numerical issues yourself either run test_control or look at the individual tests from /sw/share/octave/3.6.0/packages/control-2.4.2/test_control.m
