## Pairwise distance between 2 group of vectors (multidimensional) (Scripts) Publisher's description

### Find pair-wise SQUARE EUCLIDEAN distance

% Find pair-wise SQUARE EUCLIDEAN distance
% or 'Weighted square euclidean' distance
% between each point in A and B
% For 2 vector a, b
% Euclidean distance= d = sum((a-b).^2)
% Weighted version = d = sum(wts.*(a-b).^2)
% ------------------------------
% Input:
% A= m_by_p, m points in p-dimension
% B= n_by_p, n points in p-dimension
% Wts = 1_by_p, defaut = [1 1 ...]
% Results:
% DD= m_by_n
% ------------------------------
% Facts: (a-b)^2= a^2+b^2-2ab
