WebFKV is the core of quantum-inspired algorithms for linear algebra. Without the use of randomized methods, computing the SVD of an m× n matrix A requires O(min{m2n,mn2}) time using naive matrix multiplication. From that point onwards, computing coefficients λ and the solution vector x takes only linear time in m,n. Webalgorithms require very large-dimensional problems before it becomes preferable to employ their sampling techniques. A.
