Update of bug #31479 (project octave): Status: Confirmed => Fixed Open/Closed: Open => Closed _______________________________________________________ Follow-up Comment #17: Yes, this bug has been addressed and I will close the report. The dneupd -8 error is linked to the initial guess for the starting solution and to the number of Lanzcos basis vectors used. By supplying a static starting point for eigs through the OPTS structure I can't get it to fail with several 100K executions. Similarly, If I adjust the number of basis vectors using OPTS.p to 3 I can't get it to fail. The basis vector issue won't generally be a problem on a truly sparse matrix where the dimension N is much greater than the number of eigenvalues requested. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?31479> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
