28.03.2020 · The function will return 3 rd derivative of function x * sin (x * t), differentiated w.r.t ‘t’ as below:-x^4 cos(t x) As we can notice, our function is differentiated w.r.t. ‘t’ and we have received the 3 rd derivative (as per our argument). So, as we learned, ‘diff’ command can be used in MATLAB to compute the derivative of a function.

In this example, MATLAB ® software automatically simplifies the answer. However, in some cases, MATLAB might not simplify an answer, in which case you can use the simplify command. For an example of such simplification, see More Examples. Note that to take the derivative of a constant, you must first define the constant as a symbolic expression.
21.05.2021 · Differential or Derivatives in MATLAB. Differentiation of a function y = f (x) tells us how the value of y changes with respect to change in x. It can also be termed as the slope of a function. MATLAB allows users to calculate the derivative of a function using diff () method. Different syntax of diff () method are:
