WebTheorem(6) is the bridge between matrix derivative and matrix di er-ential. We’ll see in later applications that matrix di erential is more con-venient to manipulate. After certain manipulation we can get the form of theorem(6). Then we can directly write out matrix derivative using this theorem. 2.6 Matrix Di erential Properties = = + WebDerivatives of Expressions with Several Variables To differentiate an expression that contains more than one symbolic variable, specify the variable that you want to differentiate with respect to. The diff command then calculates the partial derivative of the expression with respect to that variable. For example, given the symbolic expression

WebJun 16, 2024 · The derivative of R ( t) is then given by R ˙ ( t) = ϕ ( t) R ( t). To derive the Lie algebra, later, it gives the 1st order expansion of R ( t) R ( t) ≈ R ( t 0) + R ˙ ( t 0) ( t − t 0) = I + t ϕ ( t 0), where t 0 = 0 and R ( t 0) = I . By given an assumption that ϕ ( t 0) = ϕ 0 around t 0, it gets R ˙ ( t) = ϕ ( t 0) R ( t) = ϕ 0 R ( t).
