Introduction to Numerical Analysis

I teach a course in numerical methods approximately every two years and am always looking for "the ideal textbook." At this time I am using "Elementary Numerical Analysis: Third Edition" by Atkinson and Han. I examined this book to determine if it would be a better selection for the course. This book covers all of the standard fare for the course: *) Fundamental analysis of computer error *) Solving linear systems of equations *) Interpolation and numerical differentiation *) Numerical integration *) Solving nonlinear equations *) Solving systems of nonlinear equations The quality of the explanations is slightly weaker than in the Atkinson book, there is nothing specific to point to; I just find the Atkinson book more readable. Algorithms in both books are expressed in Matlab code, so there is no real difference there. In conclusion, while I found that this book is certainly usable and may even be ranked as my second choice, at this time I will not be adopting in for use in my course.
