I think you might have fallen into the known Fedora Core bug in their distributed LAPACK/ATLAS libraries. Search the list for more details about the gcc "-float-store" option and where you can find rpm replacements for these files...I have installed gnu octave version 2.1.67 together with octave- forge-2004.09.09 on fedora core 3. I want to solve the eigenproblem of a non-symmetric full matrix. Octave gives me the following error: error: dgeev failed to converge. The sample problem is below. octave:1> stiff = [1,2,3,4;5,6,7,8;9,10,11,12;13,14,15,16] stiff = 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 octave:2> eig(stiff) error: dgeev failed to converge octave:2> Regards, Marino.
