This is a phenomenal effort. Virtualy anyone involved in scientific computing, from engineers, to physicists, to social scientists, will find information and methods applicable to their specific needs, or helpful subroutines that can be inserted into the reader's existing programs...No matter what language you program in, these packages are classics, both as a textbook or reference. They are an essential and valuable addition to the academic, professional, or personal library. Internet Anyone who writes (or is curious about) computer codes to solve many of the common numerical problems in science and engineering will want to own this large book. The writing is authoritative (two of the authors have published first-rate research in writing code for astrophysics problems), but never dull. Flashes of humor appear at regular intervals, in the appropriate places, and as hard as it may be to believe, this book is interesting even as casual reading! I recommend this book highly, and both the authors and the publisher are to be commended for an outstanding piece of work. Paul J. Nahin, Science Books and Films This encyclopedic book should be read (or at least owned) not only by those who must roll their own numerical methods, but by all who must use prepackaged programs. Mike Holderness, New Scientist This reviewer knows of no other single source of so much material of this nature. Highly recommended. R.J. Wernick, Choice ...will be appreciated by anyone involved in the numerical solution of engineering problems...the authors have successfully blended tutorial discussion, fundamental mathematics, explanation of algorithms, and working computer programs into neatly packaged chapters covering all of the basic topics in numerical methods. What sets this book apart, in the reviewer's opinion, is the versatility of the book...indispensable. Ben H. Thacker, Applied Mechanics Review If you already have the first edition, will you want or need the second? The answer is a definitive yes...a book that should be on your desk (not your shelf) if you have any interest in the analysis of data or the formulation of models...The second edition contains numerous additions of important material, such as a section on Cholesky decomposition (which is critical for simulating multivariate distributions), discussion of the bootstrap method, and the addition and expansion of other numerical methods too numerous to mention here. Lyle W. Konigsberg, Human Biology ...a valuable resource for those with a specific need for numerical software. The routines are prefaced with lucid, self-contained explanations...highly recommended for those who require the use and understanding of numerical software. Elizabeth Greenwell Yanik, SIAM Review ...the second [edition] expands the scope of coverage and continues the standard of excellence achieved in the first. If you were to have only a single book on numerical methods, this is the one I would recommend. Edmund Miller, IEEE Computational Science & Engineering
