Webthe derivative of one vector y with respect to another vector x is a matrix whose (i;j)thelement is @y(j)=@x(i). such a derivative should be written as @yT=@x in which case it is the Jacobian matrix of y wrt x. its determinant represents the ratio of the hypervolume dy to that of dx so that R R f(y)dy = WebNov 9, 2024 · Hi, I would like to ask a simple question about how autodiff works for vector/matrix. For an instance, if we have C = A.*B where A, B, C are all matrices. When calculating the jacobian matrix of C w.r.t A. does autodiff expand C=A.*B into C_ij= A_ij * B_ij and calculate derivative, or autodiff keeps a rule about this and directly form a … WebSep 6, 2024 · Vector by vector derivative When taking the derivative of a vector valued function with respect to a vector of variables, we get a matrix.
