# Low-Rank Approximations Book

I am looking for a source (book, online book, etc..) where I can find the theory behind low-rank approximations of matrices. In particular, I am interested in low-rank approximations used in optimization problems, such as minimizations of the Euclidean and Forbenius norms.

I have some background in basic and numberical linear algebra, but I am looking for a source that is simple and straightforward.

Sincerly, Amit.
