WebFeb 7, 2024 · 1 Answer Sorted by: 1 Taking a derivative with respect to vec ( V) T will just give us a rearranged version of the derivative with respect to V. For the derivative with respect to V, we could use the chain rule along with the matrix calculus result ∂ V ∂ V = adj ( V) = V ⋅ V − 1, where adj denotes the adjugate matrix. From there, WebDefinition. An complex matrix A is Hermitian(or self-adjoint) if A∗ = A. Note that a Hermitian matrix is automatically square. For real matrices, A∗ = AT, and the definition above is just the definition of a symmetric matrix. Example.
