ng answer will be fined worth a correct answer. If a real matrix A satisfies A" - - A then it is diagonalizable by a unitary matrix. If A is diagonalizable then all of its eigenvalues must be distinct (ie. each eigenvalue has multiplicity 1). IH A and B represent same linear transformation T : R" -→ R" then they have the same rank. If A is singular then its exponential e is also singular. Consider an LDU decomposition of a square matrix A. The product of the diagonal entries of the diagonal matrix D is the determinant of A.
