Web1 de jan. de 2024 · The first step constructs an H 2 matrix representation of K ( X, X) for a given set of particles X. By using the proxy surface method, the cost of this step is linear in the number of particles. The second step performs the H 2 matrix-vector multiplication with a multiplicand f, which also has linear cost.
