Orthogonal Sets and Polar Methods in Linear Algebra

A unique, applied approach to problem solving in linear algebra
Departing from the standard methods of analysis, this unique book presents methodologies and algorithms based on the concept of orthogonality and demonstrates their application to both standard and novel problems in linear algebra. Covering basic theory of linear systems, linear inequalities, and linear programming, it focuses on elegant, computationally simple solutions to real-world physical, economic, and engineering problems. The authors clearly explain the reasons behind the analysis of different structures and concepts and use numerous illustrative examples to correlate the mathematical models to the reality they represent. Readers are given precise guidelines for:
* Checking the equivalence of two systems
* Solving a system in certain selected variables
* Modifying systems of equations
* Solving linear systems of inequalities
* Using the new exterior point method
* Modifying a linear programming problem
With few prerequisites, but with plenty of figures and tables, end-of-chapter exercises as well as Java and Mathematica programs available from the authors' Web site, this is an invaluable text/reference for mathematicians, engineers, applied scientists, and graduate students in mathematics.
 
Dieses Lehrbuch der linearen Algebra für fortgeschrittene Studenten konzentriert sich in erster Linie auf Anwendungen. In einem unkonventionellen Ansatz betont der Autor vor allem die Zusammenhänge zwischen mathematischem Formalismus und physikalischer Realität: Einer der vier Teile des Bandes beschäftigt sich ausschließlich mit Beispielen aus der Mathematik, Physik und Ingenieurtechnik. Mit Codebeispielen in Mathematica und Java. (04/99)
