Follow-up Comment #26, bug #42097 (project octave): The next thing I would try is to run both your small test program and Octave with gdb and then step in to the dgeev call and ask for a stack trace. Then I think you should be able to verify that they are both actually using the same LAPACK library. You could also set a breakpoint for one of the BLAS library functions that DGEEV calls and then also verify that they are both using the same BLAS library. Beyond that, if you compiled the BLAS and LAPACK libraries yourself, then you can step through the two programs side by side and find where the computation goes wrong in one but not the other. That might give some clues about what is going wrong. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?42097> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
