WebSVD is usually described for the factorization of a 2D matrix A . The higher-dimensional case will be discussed below. In the 2D case, SVD is written as A = U S V H, where A = a, U = u , S = n p. d i a g ( s) and V H = v h. The 1D array s contains the singular values of a and u and vh are unitary. jersey flock reviews
