Syms diff

WebMATLAB provides the diff command 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) = 3t 2 + 2t-2. Example. Create a script file and type the following code into it −. syms t f = 3*t^2 + 2*t ...
