WebNotions of Matrix Differentiation. There are a few standard notions of matrix derivatives, e.g. If f is a function defined on the entries of a matrix A, then one can talk about the matrix of partial derivatives of f. If the entries of a matrix are all functions of a scalar x, then it makes sense to talk about the derivative of the matrix as the ... WebA tag already exists with the provided branch name.
