[Octave-bug-tracker] [bug #60818] delaunayn - 2D code path vectorization doesn't match nD algorithm

[anonymous]

Follow-up Comment #38, bug #60818 (project octave):

Fixed the slow line by changing it to


[~, rev_sort] = sort (reordered_tri_idx);
vol = prod (reshape (R(rev_sort), dim, nt), 1).';


I have not checked the speed but I expect faster with less memory used. Also
placed the missing abs() on the 3D volume calculation.
