How to derivate in matlab
WebAug 12, 2024 · In order to find derivate of quaternion, I am using fnite difference, but as far I understood I needed of 2 values in order to compute the "difference", but in ode integration at each step I comput only 1 ( istant value). WebMATLAB provides the diffcommand for computing symbolic derivatives. In its simplest form, you pass the function you want to differentiate to diff command as an argument. For example, let us compute the derivative of the function f(t) = 3t2+ 2t-2 Example Create a script file and type the following code into it − syms t f = 3*t^2 + 2*t^(-2); diff(f)
