Let a be a non-zero real matrix of order n (n > 2), and each element is equal to its algebraic cofactor in deta


Deta = 0, or deta = 1
If each element is equal to its algebraic cofactor in deta, then a is equal to its adjoint matrix A *, that is, a * = a, and AA * = deta * e, where e is the identity matrix
So det (AA *) = deta * dete, DET (AA) = deta * dete, detadeta = deta,
Deta (deta-1) = 0, so
Deta = 0, or deta = 1
