Concise but wide-ranging, this text provides an introduction to methods of approximating continuous functions by functions that depend only on a finite number of parameters — an important technique in the field of digital computation. Written for upper-level graduate students, it presupposes a knowledge of advanced calculus and linear algebra. 1969 edition.
Customer Review: Clear, concise, and complete
This is a great book for getting started with approximation theory. All you really need to do this book is a decent background in calculus and linear algebra: all the functional analysis and other tools you need are provided in the book. The only drawback to the book is that it's out-of-date and no longer reflects current research, but it does a great job in covering all the basics you'll need to understand the new, advanced stuff when you go looking for it in other books and journals. Still, this book is indispensable and I would recommend it over every other book I've seen in the field if you're new to approximation theory.
Customer Review: Great book ...
The book is terrific ... I just want to know what a "dress reversal" is - as mentioned by a previous reviewer. Maybe I missed something!!
