I came across this very interesting book titled “Introduction to Applied Linear Algebra – Vectors, Matrices, and Least Squares” by
Stephen Boyd and Lieven Vandenberghe and published by Cambridge University Press.
On the book’s website you can find a pdf file of the book for download. You can also purchase it at a (virtual) bookstore.
Additionally, you can find there more exercises and a Julia language companion.
I think this is a great book and the companion materials are very helpful. I strongly recommend those interested in learning Julia to go over the companion material.
