13 Approximation of Derivatives This section about derivatives is particulary important from a practical point of view. It often seems to be the case that either it is nearly impossible or the user has difficulties in coding the derivatives. For information about supplying partial derivatives see the Prob parameter CheckNaN in Appendix A.

Use the diff function to approximate partial derivatives with the syntax Y = diff (f)/h, where f is a vector of function values evaluated over some domain, X, and h is an appropriate step size. For example, the first derivative of sin (x) with respect to x is cos (x), and the second derivative with respect to x is -sin (x).

08.04.2021 · Numerical Differentiation using MATLAB . The MATLAB function diff can used to compute approximate derivatives . The diff function when used with a single argument returns a vector length one less than the original of the differences of the adjacent values in the vector . For example, diff(x) returns [x(2)-

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.
