Efficient pre-processing in the parallel block-Jacobi SVD algorithm

One way, how to speed up the computation of the singular value decomposition of a given matrix A ∈ C m × n , m ⩾ n , by the parallel two-sided block-Jacobi method, consists of applying some pre-processing steps that would concentrate the Frobenius norm near the diagonal. Such a concentration should...
