It comes with a test script. But, let me reiterate: libflann appears to be an orphaned and possibly obsolete project. If I restart fiddling with metric space trees again, I'll make sure to put it in my githubs. -SL If you could mention a relevant test, someone could check whether it's valid on

If you could mention a relevant test, someone could check whether it's valid on older versions of J. (The J package release process is versioned against the J engine.) Thanks, -- Raul On Tue, Mar 10, 2020 at 7:27 PM Scott Locklin wrote: > FWIIW I wrote the original version of this. Never tri

FWIIW I wrote the original version of this. Never tried to build FLANN on windows (I've never run J on windows), so no idea what it does there. I haven't touched it in a long time, but I confirm there is something wrong with it on my laptop/flann1.9/ubuntu 18.04 LTS and J901. Either something in t

I tried on my debian but the shared library had some dependency issue and couldn't run. The api of 1.7 and 1.8 were different. I don't know if that of 1.8 and 1.9 are the same or not. I couldn't test. Tue, 03 Mar 2020, Ben Gorte написал(а): > > I think the addon needs update, the old version of

Was this addon not available for Windows installations? I don't see it under my J901,  nor J807,  nor my remnants of 806 or 805. Google suggests it's for nearest neighbours - though there doesn't seem to be anything helpful arising from searching for "flann" in the J Wiki. Cheers, Mike On 02

You have probably already alerted the relevant parties but if there is documentation on the wiki, you can update it yourself or ask someone else to do it if you supply the necessary info. On Sun, Mar 1, 2020 at 9:40 PM Ben Gorte wrote: > Hi, > > a new version of the math/flann add-on appeared in

Hi, a new version of the math/flann add-on appeared in the package manager, but if gives me an error: 'n d' =: allsearch A;R;1 |domain error: cd | cmd cd dataset;rows;cols;testset;trows;index;dists;nn;params (nothing wrong with A and R) I think this is due to the changes in cd (15!:0)
