Let A be a Hermitian nxn matrix. Let the column vectors of the nxn matrix S be comprised of the orthnormalized eigenvectors of A(adsbygoogle = window.adsbygoogle || []).push({});

Again, Sinv is the inverse of S

a) Show that S is unitary

b) Show that Sinv(A)S is a diagonal matrix comrpised of the eigenvalues of A

No idea how to start this one off.
