WebApr 4, 2024 · A is an n × m matrix and Z is a vector with m entries. This means, to specify a derivative, you need three coordinates: the (i, j) for the entry of A and k for the choice of variable for the derivative. Therefore, ∂A ∂Z is really a 3 -tensor, and a 3 -tensor times a … WebThus, the derivative of a matrix is the matrix of the derivatives. Theorem D.1 (Product dzferentiation rule for matrices) Let A and B be an K x M an M x L matrix, respectively, …
