"WebSurprisingly, even for 2×2 matrices it is not completely trivial to show that that if A∈ M2(C[a,b]) is hermitian with distinct eigenvalues, then there is a unitary U∈ M2(C[a,b]) such that U∗AUis diagonal. In fact, for 2× 2 matrices we provide an algorithm for diagonalization in case where the two eigenvalues are distinct. " - Diagonalization hermitian matrix
