Update of bug #49940 (project octave): Status: Fixed => Confirmed Open/Closed: Closed => Open Depends on: => bugs #55564 _______________________________________________________ Follow-up Comment #7: Re-opening this bug report. The 'gesdd' driver can occasionally produce utterly incorrect values. so switching to this driver for performance improvement is no longer a possibility. See bug #55564 which is now linked to this report. Until bug #55564 is resolved upstream in LAPACK, it would be worthwhile to benchmark/profile Octave to determine if there is anything on our side of the API that can be improved with respect to performance. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?49940> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
