Derivative of determinant wrt matrix
WebApr 16, 2011 · 1. First note that. det (A+O'XO) = exp (tr (log (A+O'XO))) Then define the matrix partial derivative d X such that. d X tr (X n) = n X n-1. In terms of components, … WebIn the case of the metric, this implies that − det ( g + δ g) ≈ − det ( g) [ 1 + g a b δ g a b] and so δ ( − g) = ( − g) g a b δ g a b. To complete the calculation you'll then have to relate δ g a b to δ g a b, but this should get you on your way. If this isn't a homework problem or the like, let me know and I can expand on this latter part. Share

WebDec 16, 2024 · Remember that the derivative is nothing but the slope of a function at a particular point. If we take the multivariate function f (x, y) = x^2 + 3y f (x,y) = x2 + 3y The derivative with respect to one variable x will give us the slope along the x dimension. \frac {\partial {f (x,y)}} {\partial {x}} = 2x ∂ x∂ f (x,y) = 2x http://cs231n.stanford.edu/vecDerivs.pdf
WebMay 27, 2015 · So, a derivative of a sum is the same as a sum of derivatives. Hence, you simply differentiate the function (i.e. density) under the integral, and integrate. This was my bastardized version of the fundamental theorem of calculus, that some didn't like here. Here's how you'd do it with the normal probability. Webvectors, however, the more general matrix case is not considered. In [13], they find derivatives of scalar functions with respect to complex-valued matrices, however, that paper could have been simplified a lot if the proposed theory was utilized. Examples of problems where the unknown matrix is a complex-valued matrix are wide ranging
