Solution WebThe derivative of trace or determinant with respect to the matrix is vital when calculating the derivate of lagrangian in matrix optimization problems and finding the maximum likelihood estimation of multivariate gaussian distribution. Matrix-Valued Derivative.
WebFrom what I understand the general form to get the second partial derivative test is the determinant of the hessian matrix. I asume the H relations still work out, though I don't think the saddle points could still be called saddle points since it wouldn't be a 3d graph any more. If I'm wrong corrections are appreciated.

WebDerivation Using Completing the Square Technique Let us write the standard form of a quadratic equation. ax2 + bx + c = 0 Divide the equation by the coefficient of x2, i.e., a. x2 + (b/a)x + (c/a) = 0 Subtract c/a from both sides of this equation. x2 + (b/a)x = -c/a Now, apply the method of completing the square.
Web§D.3.1 Functions of a Matrix Determinant An important family of derivatives with respect to a matrix involves functions of the determinant of a matrix, for example y = X or y = AX .
