Numerical Recipes in C: The Art of Scientific Computing, Second Edition
"...an instant `classic,' a book that should be purchased and read by anyone who uses numerical methods..."   American Journal of Physics"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"The new book exceeds, if possible, the excellence of its predecessor:  it is about 50 percent longer and has been thoroughly updated...The bibliographical material has been considerably extended and updated...For new users, it is sufficient to say that practically every aspect of numerical analysis is covered...This monumental and classic work is beautifully produced and of literary as well as mathematical quality.  It is an essential component of any serious scientific or engineering library."    A. D. Booth, Computing Reviews"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."    Lyle W. Konigsberg, Human Biology"...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"...remarkably complete...it contains many more routines than many commercial mathematics packages..."   Byte"The authors are to be congratulated for providing the scientific community with a valuable resource."   The Scientist"...replete with the standard spectrum of mathematically pretreated and coded/numerical routines for linear equations, matrices and arrays, curves, splines, polynomials, functions, roots, series, integrals, eigenvectors, FFT and other transforms, distributions, statistics, and on to ODE's and PDE's...such an education...is delightful..."
