Hi,
I have multiple coordinates points which I want to get the minimum distance between point 1 to nearest other point and so on and if the distance not in the range of 55 to 85 exclude that point from cluster. I tried pdist and pdist2 and it gave me the distance from point 1 to others I don't know how to include only the desired distance which is only between 55 to 85
I attached the mat file for the coordinate points
Thanks for helping

How about the following solution?
load('xy_coordinate.mat');
% Calculate distance between each node
D = pdist(xy);
% Convert variable D into square form
Z = squareform(D);
% Extract edges having length of 55~85
idx = Z >= 55 & Z <= 85;
Z(~idx) = 0;
% Convert it into graph object
G = graph(Z);
% Visualize the result
figure
plot(G,'EdgeLabel',G.Edges.Weight)
