Derivative of a function of matrices product with respect to a single matrix












0












$begingroup$


I am reading a paper and cannot understand some math that deals with a derivative of a function of matrix multiplication with respect to a single matrix.



Can someone explain me how this is calculated
enter image description here



Last matrix is a vector, thus $w_{prod}$ is a vector.
E.g what calc and linear algebra rules are used here and how we get this final derivative.



Thank you!
