Gradiant of XAY with respect to A How can I find the gradient of the following function with respect to A?
$$
F(A) = X^T \cdot A \cdot Y
$$
Where X and Y are mx1 vectors and A is mxm matrix

To add to Robert's answer slightly, note $X^T\Delta A Y$ is the inner product (matrix component wise) of $XY^T$ with $\Delta A$ so if you vectorize the gradient, the $i,j$ term of the gradient is $X_i Y_j$ ($i$ is row and $j$ is column)
