SpletThis representation is computed via the singular value decomposition of the adjacency matrix, A=UDV^T A = U DV T .In the case, where the graph is a random dot product graph generated using latent position vectors in R^ {no} Rno for each vertex, the embedding will provide an estimate of these latent vectors. SpletThe singular values are always real numbers. If the matrix A is a real matrix, then U and V are also real.
