From the reviews of the first edition:
JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION
"…written as a companion to his earlier book titled MATRIX ALGEBRA FROM A STATISTICIAN’S PERSPECTIVE…this is not just a solutions manual. With 15 pages of definitions and terminology and another 5 pages of notations, the book can be used as an independent reader on advanced topics in linear algebra…when used in conjunction with his earlier book, provides a more in-depth second course on this topic."
"This book collects the exercises from the author’s Matrix algebra from a statistician’s perspective, (Springer 1997) and includes their solutions. … It can be used as a stand-alone book with an inspiring collection of exercises … ." (Adhemar Bultheel, Simon Stevin Bulletin, Vol. 10 (2), 2003)
"The author has collected well over 300 exercises from his earlier book Matrix Algebra From a Statistician’s Perspective into a separate volume and he added solutions. The book also contains extensive and detailed summaries of the relevant terminology and notation. … It will be very useful for any teacher of a linear algebra course as a source of exercises of various levels of difficulty." (European Mathematical Society Newsletter, December, 2003)
"This book comprises well over 300 exercises in (real) matrix algebra and their solutions. … it represents a valuable resource for any reader trying to gain some practice in the concepts of matrix algebra and looking for suitable exercises accompanied by solutions." (A. Kräuter, Internationale Mathematische Nachrichten, Vol. 57 (193), 2003)
"This book is a supplement to the author’s previous book (Harville 1997) and contains the solutions to more than three-hundred exercises taken from it. … This book is especially useful for anyone interested in dealing with proof techniques and tricks concerning matrix algebra. … For everybody who finds pleasure in reading and learning from Harville’s text, this book will have a similar effect and should be viewed as a very useful supplement."
