Approximation Techniques for Engineers: Second Edition
暫譯: 工程師的近似技術：第二版

本書第二版包含了基於矩陣函數近似的十一個新章節，涵蓋了縮減解空間和提高近似解準確性的內容、常微分方程系統初值問題的迭代解法，以及邊值問題的試探函數法。兩個新章節的主題為積分方程和數學優化。本書提供了可供手動計算的替代解法，以驗證由「黑箱」求解器獲得的結果。它還深入探討了許多行業中計算機輔助設計（CAD）和計算機輔助工程（CAE）工具背後的數學原理。本書旨在提供各種近似技術的實用知識，以便於工程實踐。

Dr. Komzsik is a graduate of the Technical University and the Eötvös University of Sciences, both in Budapest, Hungary. He worked for the Hungarian Shipyards in Budapest during the 1970s as an engineering analyst. After immigrating to the U.S., he worked for the McDonnell-Douglas Corporation between 1981-1982 as a senior analyst. Following that, he spent two decades as Chief Numerical Analyst at the MacNeal-Schwendler (now MSC Software) Corporation. After another decade and a half, he recently retired as Principal Key Expert from Siemens PLM Software.

He is the author of the original NASTRAN Numerical Methods Handbook, and a widely read book on The Lanczos Method that was also published in Chinese, Japanese, and Hungarian. His books titled "Computational Techniques of Finite Element Analysis" and "Applied Calculus of Variations for Engineers and Approximation Techniques for Engineers" are already in their second editions. He is also the co-author of the book, "Rotor Dynamics with Finite Elements."

Dr. Komzsik 是匈牙利布達佩斯技術大學和厄爾特大學的畢業生。他在1970年代於布達佩斯的匈牙利造船廠擔任工程分析師。移民到美國後，他於1981年至1982年間在麥克唐納-道格拉斯公司擔任高級分析師。隨後，他在麥克尼爾-施文德勒（現為MSC Software）公司擔任首席數值分析師，工作了二十年。再過了一個半十年，他最近從西門子PLM軟體公司退休，擔任首席關鍵專家。

他是原版 NASTRAN 數值方法手冊的作者，並且撰寫了一本廣受歡迎的《蘭茨科斯方法》書籍，該書也已出版中文、日文和匈牙利文版本。他的書籍《有限元素分析的計算技術》和《工程師的變分法應用與近似技術》已經進入第二版。他也是《有限元素的轉子動力學》一書的共同作者。
