Preface I am happy for you to see this Fifth Edition of Introduction to Linear Algebra. This is the text for my video lectures on MIT¡¯s OpenCourseWare (ocw.mit.edu and also YouTube). I hope those lectures will be useful to you (maybe even enjoyable !). Hundreds of colleges and universities have chosen this textbook for their basic linear algebra course. A sabbatical gave me a chance to prepare two new chapters about probability and statistics and understanding data. Thousands of other improvements too¡ª probably only noticed by the author. . . Here is a new addition for students and all readers: Every section opens with a brief summary to explain its contents. When you read a new sec...
