Find the functional derivative of the functional S [ y] = ∫ b a y ( x) sin ( y ( x)) d x with respect to the function y, where the integrand is f [ y ( x)] = y ( x) sin ( y ( x)). Declare y (x) as a symbolic function and define f as the integrand of S. Use f and y as the parameters of functionalDerivative.

MATLAB contains a variety of commands and functions with numerous utilities. This article is focussed on understanding how MATLAB command ‘diff’ can be used to calculate the derivative of a function. ‘diff’ command in MATLAB is used to calculate symbolic derivatives. In its simplest form, a function, whose derivative we wish to compute, is passed as an argument to the diff command.

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.
