L2 norm in r

WebAug 1, 2024 · It is really for matrix norm. When you do norm (cbind (x1, x2), "2"), it computes the L2 matrix norm which is the largest singular value of matrix cbind (x1, x2). So my problem is with defining s. Ok, what if I have more than three vectors? In that case you want pairwise Euclidean matrix. See function ?dist.
