Title: Linear circuit analysis by symbolic algebra
Abstract: Using the ALPAK system for symbolic algebra, a package of three subroutines, SYMCIR, was developed as a research tool in linear circuit analysis. Though restricted in scope to computing basic circuit functions, the programs were designed to be used on an operational, not experimental basis. As a result, problem areas were discovered which have no analogue in numerical computation. These were encountered because of the mathematical structure of the problem, and are software-independent. The techniques used to overcome these difficulties are hence of interest to all programmers using symbolic languages for mathematical computations. Some difficulties in analyzing the final results of the computation were encountered because of their complexity. Some methods of alleviating this difficulty are discussed.
