Based on the title and description of this book, I bought it hoping to learn more about developing financial tools, specifically interest rate models, in Matlab. After working through most of the book, I have concluded that the use of the name "Matlab" in the title is misleading: it only means that Maple, the main tool of the book, may be accessed via the kernel of Matlab.
The book appears to be targeted primarily at undergraduates and MBA students, not practitioners in the field. Such an audience may have little interest (or need) in learning to develop code or the intricacies of the underlying mechanics of financial models, and for them, the book would no doubt be very helpful. The software that comes with the book includes a stripped down version of Maple, (which is nice, since you can't really use the book without it), and author-developed analytical tools. These tools support the goals of learning through the ability to quickly vary inputs and see the impact on the output, but as they are more or less a black-box, do not add much to one's independent ability to model new financial objects or extend existing ones.
The book includes the de rigueur definitions of typical financial instruments and explanations that facilitate understanding of these instruments (such as how to read and understand option data in newspapers, the mechanics of currency swaps and so on), but one really has to follow along with the Maple commands page by page to derive benefit. The fixed income section is very skimpy. It seems like the book is best suited as an extended set of lecture notes.
I like the book but would not recommend it to practioners looking for insight on tool development or to extend knowledge of cutting edge interest rate models (as these are not covered here). I would recommend it for newcomers to the field having mathematical or quantitative backgrounds who want a reasonably good introduction to financial instruments. It would also be useful as a companion text in master's programs in financial engineering or financial mathematics. Derivatives and Maple with training wheels.
