Review title: Did anyone actually edit this book?
Product review: I find it appalling that in a college level textbook there would be spelling errors, problems that just don't make sense (i.e. a problem referring to making four plots but failing to say what they should be of), and untested matlab scripts. This book looks like it was written on a whim and doesn't really cover matlab, it just presents mathematical problems that should be solvable in matlab, but without providing any examples or information in the text to help.
