Derivative of a matrix times a vector
WebMost generally, a vector is a list of things. In multivariable calculus, "thing" typically ends up meaning "number," but not always. For example, we'll see a vector made up of … WebIt is a well-known result that the time derivative of a rotation matrix equals the product of a skew-symmetric matrix and the rotation matrix itself. One classic method to derive this result is as follows [ 1, Sec 4.1], [ 2, Sec 2.3.1], and [ 3, …
