WebOrthogonal matrices are the most beautiful of all matrices. A matrix P is orthogonal if PTP = I, or the inverse of P is its transpose. Alternatively, a matrix is orthogonal if and only if its columns are orthonormal, meaning they are orthogonal and of unit length. An interesting property of an orthogonal matrix P is that det P = ± 1.
