image - Vectorizing distance calculation between vectors -

i have 3 x 1000 (and later 3 x 10 000) matrix cord given, contains 3 dimensional coordinates pixels.

my intention calculate distance between pixels, , loop (see below), have calculate huge matrices soon, , wondering if vectorize code making faster...?

dist = zeros(size(cord,2),size(cord,2)); = 1:size(cord,2) j = 1:size(cord,2) dist(i,j) = norm(cord(:,i)-cord(:,j)); dist(j,i) = dist(i,j); end end

pdist that. squareform needed result in form of square, symmetric matrix:

dist = squareform(pdist(cord.'));
