ABSTRACT

The system equation obtained in this section, Eq. (9.28), can be solved by either a direct method (e.g., Gauss elimination) or an iterative method (e.g., successive-overrelaxation). The results presented in the remainder of this section were obtained by Gauss elimination. Iterative methods for solving the system equation are presented in Section 9.6.
