I’m hoping readers will contribute reviews on amazon as for the first book. Goodreads gives it a 4.3/5.

In the meantime here are some snippets from feedback I’ve received by email:

• I bought your ebook for a linear systems engineering class last year. It was fantastic and actually EXPLAINED the concepts in a way that gives a strong intuitive understanding. I was able to get an A+ thanks to your great book. So many thanks for your efforts.
• It is a delight to read.
• Your linear algebra book is truly beautiful. […] I can see that you’ve spent a lot of time developing it. […] I can remember that learning linear algebra for the first time was a joyful experience for me, and when skimming your book […] to relive some of those feelings.
• I have been looking for learning materials which would meet my needs with limited success. When I reviewed the sample pages of your books, I quickly realized that I had stumbled on a mother lode.
• Thank you for writing an awesome book. I’m working through it. :)
• It’s dense, but in a good way, has useful and intuitive explanations, and contains all necessary formulas. It will be good reference book also.
• Well done. Thanks for this unique perspective on linear algebra.
• I have read half this book so far and everything has been crystal clear.
• An outstanding textbook for any course involving Linear Algebra. I’ve referenced this book in multiple big data courses when I’ve needed a deeper understanding of the material.
