Lanczos Method

Louis Komzsik has worked for 30 years in the structural analysis industry, the past 20 years as Chief Numerical Analyst at MSC. Software, where he was responsible for the development of the numerical methods employed in NASTRAN, the world's leading commercial finite element solver. He is currently working on an automated version of NASTRAN at Schaeffer Automated Simulation, where he is Chief Numerical Analyst. Dr. Komzsik is a member of MAA and a participant in SIAM's Visiting Lecturer program. He is also a lecturer at California State University at Long Beach.

'I recommend this book to anyone who wants to appreciate the often subtle interactions between algorithm research and engineering applications. For the engineer, it comprehensively summarizes 25 years of intellectual development in the understanding of the basic Lanczos algorithm and its many variants. For the numerical analysts, it describes the variety of practical considerations, which are of critical importance in such applications as structural analysis.' Horst Simon, Director, NERSC Division, Berkeley National Laboratory 'Detailed development of the method and its algorithmic structure, illustrations by industrial grade examples make this book a welcome addition to the literature on this important subject. The book is a valuable reference ...' Barna A. Szabo, Professor of Mechanics, Washington University, St. Louis 'The Lanczos method is perhaps the least understood numerical technique used on a daily basis by structural analysts. This book illuminates the mysteries of the method and its real-world examples demonstrate its relevance.' Albert Danial, Application Engineer, TRW, Inc.
