WebMar 12, 2024 · A matrix exponential can also be defined in exact analogy to the exponential function. The matrix exponential of a matrix A A can be expressed as. eA = 1+A+ A2 2! + A3 3! +⋯ e A = 1 + A + A 2 2! + A 3 3! + ⋯. This is important because quantum mechanical time evolution is described by a unitary matrix of the form eiB e i B for Hermitian ... Webmatrix. Therefore A is similar to a real diagonal matrix. Just let S = I to get A is Hermitian. Theorem 9.0.5 (Spectral Theorem). Let A ∈M n be Hermitian. Then A is unitarily (similar) equivalent to a real diagonal matrix. If A is real Hermitian, then A is orthogonally similar to a real diagonal matrix. 9.1 Variational Characterizations of ...
