Title: need help with Linear Algebra concepts!!!!
Post by puzzlecracker on Nov 3^rd, 2004, 12:35pm

I don't much remember from my wistful undergrad days in Algebra classes.

I need quick but easy to understand and comprehensive reference to:

a) Unitary matrices, unitary transformations.

b)Eigenvectors, eingenvalues, its operations

c) Tensor products, operations, etc

I got entangled with quantum computations and been losing my mind due to the lack of knowledge in Elementary Algebra.

Thanks guys.

You may want to look at the following collection (http://books.pdox.net/Math/) of math sourcres.

Also, googling "linear algebra" "lecture notes" gives some interesting links.

Hope this helps.
