Follow-up Comment #13, bug #61754 (project octave):
I made a few small changes to follow Octave coding conventions here
(http://hg.savannah.gnu.org/hgweb/octave/rev/95ee9b9605cc).
I did a minimal check on performance with
z = rand (1e3, 1e3);
tic; zi = interp2 (z, 2, "cubic"); toc
Result was 0.8 seconds. Seems fine for me, but I don't know what size
datasets people usually use. I think I did notice a for loop which might be
slow. Since there is a kernel being applied would conv2() or filter2() be
faster alternatives?
