If you want the normal adjoint (the conjugate transpose), then x' will give it to you for x. (The non-conjugated transpose is x.', or transpose(x).conj(x) gives the complex conjugate, and works on matrices and vectors as well.) If you actually want the adjugate (aka classical adjoint), I …

WebJul 26, 2024 · Right now I am guessing that when we consider all complex matrices, A T means A conjugate transpose and not simply transpose. So in the question, they meant A ¯ T. In which case, det ( A T − λ I) = det ( ( A − λ ¯ I) T) = det ( A − λ ¯ I) So my understanding is that the transpose operation causes the eigenvalues to be conjugated. WebDec 23, 2024 · Another consequence of all this, as you said, is that the correct choice for you determinant formula is the entry-wise transpose rather than the conjugate transpose. In this case, the formula for the cofactor matrix bears no relation to the Euclidean geometry on $\Bbb R^n$ or $\Bbb C^n$.
