Derivative of matrix transpose

WebMay 9, 2024 · To compute the derivative of the determinant of A, you form the following auxiliary matrices: D 1 = {0 1, ρ 1}. The first row of D 1 contains the derivatives of the first row of A. The determinant of D 1 is det (D 1) = -ρ. D 2 = {1 ρ, 1 0}. The second row of D 2 contains the derivatives of the second row of A.
