For efficiency reasons, the euclidean distance between a pair of row vector x and y is computed as: dist (x, y) = sqrt (dot (x, x)-2 * dot (x, y) + dot (y, y)) This formulation has two advantages over other ways of computing distances. In Python terms, let's say you have something like: plot1 = [1,3] plot2 = [2,5] euclidean_distance = sqrt((plot1-plot2)**2 + (plot1-plot2)**2) In this case, the distance is 2.236.
