WebHermitian and Unitary matrices (supplement to 7.1) There is a complex version of orthogonal matrices. A complex square matrix U is called unitary if U∗ = U−1. Equivalently, the columns of U form an orthonormal set (using the standard Hermitian inner product on Cn). Any orthogonal matrix is unitary.
