Hi People,

I could really some help asap. I need to figure out how to modify the code proposed by MattJ (from a previous question) in order to find the 10 nearest points to every other point within a group of points (i.e., 10 nearest neighrbors). The points I speak of are the Fermat center points to the Triplets were found in the previous task. I have found all these "center points" and have their coordinates in the attached file (F_points.mat). Any help you could offer would be greatly appreciated.

Best

Steve

F_points.mat

Sorry about that. Here you go.

I would also like to plot the 10 closest points for each point with lines connecting them if possible. Thank you.

There is a specific routine for k-nearest-neighbour

I tried it and can't get it to do what I need.

We can't see what you tried, and so can't know what to advise further.
