**How to take a derivative with respect to a matrix Quora**

2 DERIVATIVES 2 Derivatives This section is covering diﬀerentiation of a number of expressions with respect to a matrix X. Note that it is always assumed that X has no special structure, i.e.... Matrix Derivative. Given that is a matrix that varies with time , define its Moore-Penrose pseudoinverse, . How can I find a simplified expression for in terms of ?

**How to take a derivative with respect to a matrix Quora**

29/04/1996 · Dear netters! My question is how to calculate the derivative of a determinant. The determinant is a function of 2(n-1) parameters. The matrix is... Given the prevalence of Kronecker products in matrix derivatives, it would be useful to have rules for computing derivatives of Kronecker prod-ucts themselves, i.e. dA›B=dA and dA›B=dB. Because each element of a Kronecker product involves the product of one element from A multiplied by one element of B, the derivative dA›B=dA must be composed of zeros and the elements of B arranged in a

13/12/2014 · 1. The problem statement, all variables and given/known data Find the derivative of f(X). f(X) = transpose(a) * X * b where: X is nxn a and b are n x 1... The Hessian matrix of is a -matrix-valued function with domain a subset of the domain of , defined as follows: the Hessian matrix at any point in the domain is the Jacobian matrix of the gradient vector of at the point. In point-free notation, we denote by the Hessian matrix function, and we define it as: Interpretation as second derivative. The Hessian matrix function is the correct notion of

**Hessian matrix Calculus**

In chapter 2 of the Matrix Cookbook there is a nice review of matrix calculus stuff that gives a lot of useful identities that help with problems one would encounter doing probability and statistics, including rules to help differentiate the multivariate Gaussian likelihood.... In practice one needs the first derivative of matrix functions F with respect to a matrix argument X, and the second derivative of a scalar function f with respect a matrix argument X. This is because, in practice, second-order derivatives typically appear in optimization problems and these are …
