[null,null,null,"Sommario/riassunto","Advances in computer technology have conveniently coincided with trends in numerical analysis toward increased complexity of computational algorithms based on finite difference methods. It is no longer feasible to perform stability investigation of these methods manually--and no longer necessary. As this book shows, modern computer algebra tools can be combined with methods from numerical analysis to generate programs that will do the job automatically.Comprehensive, timely, and accessible--this is the definitive reference on the application of computerized symbolic manipulations for a"]
