How can i have a vector which consists of all the distances betweeen all points of matrix? I have 3D matrix B = 151*3 with points coordinates (X,Y,Z are columns). Possible combination of all this points should be 11325(n = 151,k=2).
`I can calculate the distance between 2 3d points like this:
dist = norm(B(1,:,:)-B(2,:,:))
but unfortunately my for loop doesn't work:
n = size(B,1)
for k = 1:n-1
for a = k:n-1;
Z1 = B(k,:,:);
Z2 = B(a+1,:,:);
dist = norm(Z2 - Z1);
it returns only one number , but i want to have a vector with all distances, so i can make a histogram from it.
Where is the mistake of the for loop? Or can i solve this with repmat function?
