Follow-up Comment #4, bug #43519 (project octave): On my computer the situation is reversed and the sparse case runs much faster than the full one. With L = 2000 and the example code from comment #2, octave:1> L = 2e3 L = 2000 octave:2> eigs_perf Elapsed time is 3.27069 seconds. Elapsed time is 0.664507 seconds. This is Octave version 3.8.2 compiled from scratch running on Kubuntu 12.04. The arpack library is version 3.0.2-3. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?43519> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
