I was astonished about how good the examples are and about how much insight the author gives the reader! Pretty good book.<br>The only downside is that it does not prove important things sometimes. For example, the similarity of matrices relation is only "proven" through an example. Also, I found that at some point, the authors could explain things in more words to make them a bit clearer and more intuitive, although they do clarify everything through examples; I guess this is their way of explaining something and it gets the job done for most cases at the end of the day.<br>As far as great examples are concerned, this is the king. But for anybody-like me-wanting proofs and more mathematical insights (not only physical as this book provides in spades) I would also check out other books (like, say, one of Hassani's books).
