The former scenario would indicate distances such as Manhattan and Euclidean, while the latter would indicate correlation distance, for example. The two points must have the same dimension. Newbie: Euclidean distance of a matrix?? Recall that the squared Euclidean distance between the point p = (p1, p2,..., pn) and the point q = (q1, q2,..., qn) is the sum of the squares of the differences between the components: Dist 2 (p, q) = Σ i (pi – qi) 2. Customer2: Age = 50 | Income = 200 | Education = 8 . I'd thought that would be okay, but now that I'm testing it, I realized that this for loop still slows it down way too much(I end up closing it after 10mins). In mathematics, a Euclidean distance matrix is an n×n matrix representing the spacing of a set of n points in Euclidean space. cdist(XA, XB, metric='euclidean', p=2, V=None, VI=None, w=None) Computes distance between each pair of the two collections of inputs. 02, Jan 19.

What would happen if we applied formula (4.4) to measure distance between the last two samples, s29 and s30, for The only thing I can think of is building a matrix from c(where each row is all the centers one after another) and subtracting that to an altered x matrix(where the points repeat column wise enough time so they can all be subtracted by the different points in c). Macros were written to do the repetitive calculations on each school. And we feed the function with all the vectors, one at a time a) together with the whole collection (A): that’s the other loop which we will vectorize.
