"Dr. Komzsik's book is a rare combination of the basic knowledge in the areas of approximation and computational mechanics which is essential for an engineer. Exhaustive coverage of all the topics along with lucid presentation of the concepts and a wide variety of illustrative problems make this book a valuable source for advanced users. Logical sequence of the topics and nomenclature even allows beginners to cope with the complex field of approximation methods in science and technology. This book contains a large amount of information not found in standard textbooks. Written for the engineer involved in complex issues, it combines the modern mathematical standards of numerical analysis with an understanding on how to effectively use these abstract methods.
The new edition features integral equations and mathematical optimization methods toward their practical usage in the focus of finite and boundary element methods in solitary and coupled formulation as well."
Thomas Flöck, R&D Engineer, Siemens Digital Factory/Motion Control, Erlangen, Germany
"The first edition of Louis Komzsik's book was an extremely valuable source of numerical routines for the last decade pushing the envelope in automotive applications. We awaited this second edition book for years and looking forward utilizing it in our work.
The BMW i8 model in the picture on the front depicts the various stages of approximations during the development of a car, ranging from sketches through finite element models to the final geometry. In this process engineers use many of the methods described in this book."
Daniel Heiserer, BMW, Munich, Germany
"This book features an approachable blend of theoretical motivation with illustrative examples. Many of the methods described lend themselves to a matrix formulation, making them suitable for implementation using MATLAB®. The second edition is further improved by the inclusion of solution methods for integral equations and modern optimization applications. Almost any scientist or engineer will be able to find a topic of interest in this volume."
Leonard Hoffnung, MathWorks Inc., USA
"This book collects a wide variety of numerical approximation techniques for easy reference, with detailed examples. There is, happily, sufficient exposition for the mathematically mature reader to use "Approximation Techniques" as an introductory text. Notation is clear and consistent, and the style is elegant yet comfortable; proof computations are included when they provide valuable context and intuition, and left out when the details are too cumbersome. The new chapters describe techniques which have applications as diverse as operations research and mathematical physics, but the new edition continues to provide ample engineering context and illustration from the perspective of Dr. Komzsik's extensive experience in the field."
Gillian Grindstaff, The University of Texas at Austin, USA
"For the electronics engineer who wants to better understand numerical analysis, this book is a good fit, especially if you want to improve your matrix math ability. It has an intermediate amount of detail and the most important methods that will be found and used in power electronics, and for this reason, it can be a good book to acquire."
Dennis Feucht, How2Power Newsletter, September 2017
"The reader can find many examples of numerical analyses of technical problems. This book is especially useful in those situations when engineers need a quantitative estimation of the phenomenon under study. The book may also be useful to graduate engineering students and to all who are interested in applied numerical calculations."
