This paper illustrates the application of Wynn's vector ε‐algorithm to solve a system of equations arising in the method of moments (MoM) solution of an electrostatic problem. Since the method is iterative, it does not require inversion of a matrix. The degree of accuracy of the solution can be controlled by specifying a convergence factor. © 2003 Wiley Periodicals, Inc.
