Is there a book, monograph, lecture notes, etc. where the exposition of spectral theory is restricted exclusively to matrices? I would appreciate any suggestions, recommendations, etc.

I am not sure how interesting that theory is since every finite dimensional vector space admits a Hilbert space structure, and every linear operator is bounded and compact.
However, the Jordan/Frobenius/Smith normal forms probably give the best analog to spectral theory - and the spectral theorem for (real and complex) normal matrices. All of these can be found in any introductory linear algebra text e.g. Smith.
