A Parallel Butterfly Algorithm
The butterfly algorithm is a fast algorithm which approximately evaluates a discrete analogue of the integral transform $\int_{\mathbb{R}^d} K(x,y) g(y) dy$ at large numbers of target points when the kernel, $K(x,y)$, is approximately low-rank when restricted to subdomains satisfying a certain simpl...
