bug in fnn.m ?

Dear Marwan There seems to be a bug in fnn when computing the distance in dimension m+1(Line 536) When computing FNN ratio, the code given is if is(2) < NX & idx(i) < NX & distance(2) < x_s FNN(m,1) = FNN(m,1) + double((abs(x(idx(i)+m) - x(is(2)+m))/distance(2) > r)); cnt = cnt + 1; end My q...

k-nearest neighbour networks

Hi I am interested in generating adjacency matrices using k-nearest networks approach. I have couple of questions regarding this . 1) Assuming the embedding dimension is m, i will get m-1 adjacency matrices ( for dimension 2 to m ). I am interesting in computing some network measures like clustering...
