Abstract:	The multilevel matrix decomposition algorithm (MLMDA) has been implemented in 3-D for the solution of large electromagnetic problems. The electric field integral equation is solved for arbitrary surfaces discretized using N Rao, Wilton, and Glisson basis functions. The MLMDA accelerates the matrix–vector products in a conjugate gradient or biconjugate gradient iterative solution of the resulting system of equations. The computational cost of each iteration is proportional to N¿log2¿N for very large problems, and is particularly small for planar or piecewise planar objects. ©1999 John Wiley & Sons, Inc.
