Review title: This book is just plain bad.
Product review: Stay away from this book if you can. I've taken the author's class and tried to use the book, but it is extremely hard to follow and understand. The author just spouts page after page of cryptic Matlab scripts, leaving almost no room for explanations about important concepts. Reviewing from the book is almost impossible, since it makes no distinction in format between irrelevant information (of which there's much), and important, key topics.
