ABSTRACT
Discretization and testing of integral equations via the Method of Moments results in a linear system which must be solved numerically, and so an understanding of how to do this is necessary. Though engineers will likely not have to implement their own linear equation solver, it is useful to understand how such solvers work, what pitfalls exist, as well as what software libraries exist for helping in this task. In this chapter we will briefly describe common methods for solving linear equations such as Gaussian Elimination and LU Decomposition, as well as iterative solvers.
