Section 4.1

The most difficult part of this section was remembering everything about eigonvalues. I've never heard of a hermitian transpose of a matrix but the process seems doable. I just can't remember the syntax for Abar is though. I remember spands, basis, and independence from Math349 and I really remember doing diagonalizable matrices and similarity transformations in Math302. But I'm having trouble seeing what's the difference between an eigenvector and and eigenpair if an eigenvector is composed of eigenvalues.
