In this letter, a hybrid algorithm combining the direct method with the iterative method is designed for solving the FE–BI matrix equation, which not only can take full advantage of the multilevel fast multipole algorithm (MLFMA), but also can significantly speed up the rate of convergence. Numerical experiments demonstrate that the proposed hybrid algorithm has a significant improvement in efficiency over the conventional direct algorithm. ©2000 John Wiley & Sons, Inc.
