Robust Design Technique resources

Iterative methods. Since an objective of this book is the development of portable tools, we will not discuss direct solvers. Suffice it to say that such solvers, the most notorious being Gaussian elimination, are well documented in the literature (e g., see Carnahan, Luther, and Wilkes, 1969). We will, by contrast, emphasize iterative techniques, since these require minimal computer resources and allow the greatest flexibility. As we will show, they are also very useful in designing smart and robust algorithms. For reasons that will become obvious, let us rewrite Equation 7-15 in the form...
