Element Stamp Algorithm for Matrix Formulation of Symbolic Circuits [PDF ebook] 

The need to analyze a linear network is a recurring requirement in computer-aided network analysis. Not only are the majority of the network problems to be solved linear problems, but nonlinear resistive and dynamic networks are usually solved by the analysis of a sequence of "linearized" networks. The analysis of such networks can commonly be viewed as a two-stage process: equation formulation and linear solution. This book discusses an attractive formulation procedure that will not only change the solution strategy, but also the view of matrix reduction techniques.
