4.0 out of 5 stars A little disappointed, April 4, 2006

By	C. Lynch (Ellicott City, MD USA) - See all my reviews (REAL NAME)

I really like the format of this book, and I bought it after reading the good reviews on this site. But I have a big problem with the errors in the worked out problems and the problem answers in the book. Pages 30, 31, 64, 102, 233, 234, and 235 contain either mis-printed values or answers that are demonstrably wrong. (One can always check the solution to a set of equations by verifying that they do, in fact, solve the set of equations.) Since I am only up to page 138, there are probably more errors, as well. Given that this is supposed to be a self-teaching guide, this is a definite drawback since the student's first impulse is always to assume that the mistake is their own. Needless to say, this can result in a lot more frustration than required. Even now I'm wondering if I really just missed something, but I don't think so. A book like this really could have used better proofreading (a lot of the mistakes may simply be dropped or duplicated digits). So Caveat Emptor and Caveat Lector.

5.0 out of 5 stars A pleasant surprise, December 20, 2005

By	Working physicist - See all my reviews

After reading the author's other book Quantum Mechanics Demystified, I was curious about this work. I was quite surprised. The author's talents are topic selection and presentation. It seems linear algebra books are either theoretical or applied. While this book is clearly of the applied flavor, it steals the gems from the theoretical presentations. Most people who have had linear algebra and are not math majors see matrices as collections of numbers to solve linear systems. While the author covers the solution of linear systems, he shows that Gaussian elimination is a form of reduction which tells us about the problem, not just the solution. By the time you get through QR reduction and singular value decomposition (SVD), you will think of linear algebra in a broader sense. To me this volume corrects a common problem where practitioners think linear algebra = Gaussian elimination + determinants. He brings in the practical perspective from advanced treatments without a cumbersome theoretical framework. As for the quality of the presentation, I must say that when I compared the SVD presentation in LAD to that in Numerical Recipes, I had a strong preference for LAD. By way of critique, I would encourage the author to rework his problems so that they have integer solutions; the manipulation of complex fractions is tedious and detracts from the clarity of the presentation. In closing, this book collects the material you should have in your mind after completing a class in linear algebra.

5.0 out of 5 stars One of the hottest books on Linear Algebra, March 21, 2006

By	Joseph E. Karpinski - See all my reviews (REAL NAME)

If your looking for a book to supplement your textbook on Linear Algebra, or a book that provides a mathematical background for a course in Quantum Physics, check out this book. Many textbooks seem to be written at a level that requires the reader to already have a solid understanding of the material being presented. If you don't, you struggle through the book. How many times have you started a chapter on Vector Spaces, Linear Equations, or Matices, only to be lost after the first page or two. David McMahon does an excellent job of giving clear, step-by-step examples, as he walks you through Linear Equations, Matrix Algebra, Determinants, Vectors Spaces, and Eigenvectors. And here's the thing, you understand each topic, as you complete it. I have nothing but the highest praise for David McMahon as an author, who took the essentials of linear algebra, and presented it in a format that is easy to understand, and at the same time fun.
If you agree with this review, and are interested in building on what you learned in "Linear Algebra DeMystified", check out David McMahon's two other books, "Quantum Mechanics DeMystified" and "Relativity DeMystified".
