You need to find out about Functional analysis. Matrices are
representations of linear operators on or between (usually finite
dimensional) vector spaces. The extension to the infinite dimensional case
is not trivial. If you want a book, I suggest Kreyszig's "Introductory
functional analysis with applications", but be prepared to do a lot of
reading and thinking!
