Update of bug #57603 (project octave): Status: In Progress => Fixed Open/Closed: Open => Closed _______________________________________________________ Follow-up Comment #7: Turns out that there was a lot of room for improvement. I re-wrote a lot of quadv.m in this changeset https://hg.savannah.gnu.org/hgweb/octave/rev/6d35ab1cd544. The function now correctly handles periodic integrands. I also implemented the Richardson extrapolation algorithm which reduces the number of required function evaluations by ~3.5X. This will all be in the new 6.1 release of Octave which is probably in February. Marking as fixed and closing report. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?57603> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
