About

Overview

Renowned professor and author Gilbert Strang demonstrates that linear algebra is a fascinating subject by showing both its beauty and applications. While giving you the necessary mathematics, the book is not entirely concentrated on theorems and proofs. Strang explains rather than deduces; the emphasis is on understanding. This book is written in an informal and personal style and teaches real mathematics. In Chapter 2, the gears change as you transition to vector spaces. Throughout the book, the theory is motivated and reinforced by interesting and important applications.

Features and Benefits

  • Offers a large number of applications to physics, engineering, probability and statistics, economics, and biology. These are not tacked on at the end; they are part of the mathematics.
  • Includes an optional section on the Fast Fourier Transform. Students discover how this outstanding algorithm fits into linear algebra and introduces complex numbers.
  • Recognizes what the computer can do in linear algebra, without being dominated by it.
  • Contains a wealth of exercises that appear in the sections and in the chapter reviews.

What's New

  • The exercise sets in the book have been greatly extended and thoroughly updated. They feature many new problems drawn from Professor Strang's extensive teaching experience.
  • The writing and the plentiful new examples reflect Gilbert Strang's hallmark clear and lively style.
  • New coverage of the Singular Value Decomposition has been added to the text. The row reduced echelon form plays a larger part in the discussion of elimination. The Four Fundamental Subspaces remain central to the understanding of vector spaces in Chapter 2.
  • A second color has been added to the illustrations and boxes, many of which are new.
  • The Linear Algebra web pages offer review outlines and a full set of video lectures by Gilbert Strang. The site also includes eigenvalue modules with audio (ocw.mit.edu and web.mit.edu/18.06).
