Matrix, the one with numbers, arranged with rows and columns, is extremely useful in most scientific fields. Hermitian Matrix Link : https://www.youtube.com/watch? Similarly, the columns are also a unitary basis. In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`. A matrix U2M n is called unitary if UU = I (= UU): If Uis a real matrix (in which case U is just U>), then Uis called an orthogonal matrix. |lambda| = 1. EXAMPLE 2 A Unitary Matrix Show that the following matrix is unitary. that transpose is a much simpler computation than inverse. A similarity transformation of a Hermitian matrix with a unitary matrix gives, Unitary matrices are normal matrices.
