On skew-symmetric differentiation matrices
WebThe matrix in (1.1) is skew symmetric, yet it is a sobering thought that this second-order approximation of the derivative is as good as it gets: no skew-symmetric Web1. user8268 is right. in order to prove ‖ x ‖ is constant, just compute its derivative with respect to time. ‖ x ‖ 2 = x T x, d x T x = 2 x T d x = 2 x T A x d t. Since A is skew-symmetric, x T A x = 0. – Shiyu. Apr 2, 2011 at 11:04. @Shiyu or user8268: could you explain the differentiation step d ( x T x) = 2 x T d x?
