Involutory matrix meaning
WebWould it be true to say that if a square matrix represents an involution, i.e. A 2 = I (or A = A − 1 ), then it is Hermitian ( A = A ∗) and Unitary ( A − 1 = A ∗ ). The reverse implication is definitely true, but is it an equivalence? If so, then why? And if not, could it be true for real matrices? (Involution ⇒ Symmetric & Orthogonal) Web24 mrt. 2024 · 1. If A is an n × n involutory matrix, then show that. det ( A) = ( − 1) n − tr ( A) 2. A matrix is involutory if it is its own inverse, A − 1 = A. Thus, the eigenvalues of …

WebA unitary matrix is a matrix, whose inverse is equal to its conjugate transpose. Its product with its conjugate transpose is equal to the identity matrix. i.e., a square matrix is unitary if either U H = U -1 (or) U H U = U U H = I, where U H is the conjugate transpose of U.

We establish several rank equalities for idempotent and involutary matrices. In particular, we obtain new formulas for the rank of the difference, the sum, the product and the commutator of idempotent or involutary matrices. Extensions to scalar-potent matrices are also included.
