"Using an H-2 matrix as the mathematical framework, we compactly represent a dense system matrix by a reduced set of parameters, thus enabling a significant reduction in computational complexity. The error bound of the H-2-matrix-based representation of an electrodynamic problem was derived," investigators in the United States report.
"We show that exponential convergence with respect to the number of interpolation points can be achieved irrespective of the electric size. In addition, we show that a direct application of H-2-matrix-based techniques to electrodynamic problems would result in a complexity greater than O(N), with N being the matrix size, due to the ...
