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.

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.

08.04.2020 · Derivative in Matlab. Let’s consider the following examples. Example 1. Example 2. Example 3. To find the derivatives of f, g and h in Matlab using the syms function, here is how the code will look like. syms x f = cos(8*x) g = sin(5*x)*exp(x) h =(2*x^2+1)/(3*x) diff(f) diff(g) diff(h)

G = functionalDerivative( f , y ) returns the functional derivative δ S δ y ( x ) of the ...

Here is how to handle derivatives in Matlab. Use this command to find a derivative in Matlab with no hassle.

How Does MATLAB Derivative Work?

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.

To determine the default variable that MATLAB differentiates with respect to, use symvar: symvar (f, 1) ans = t. Calculate the second derivative of f with respect to t: diff (f, t, 2) This command returns. ans = -s^2*sin (s*t) Note that diff (f, 2) returns the same answer because t is the default variable.

To determine the default variable that MATLAB differentiates with respect to, use symvar: symvar (f, 1) ans = t. Calculate the second derivative of f with respect to t: diff (f, t, 2) This command returns. ans = -s^2*sin (s*t) Note that diff (f, 2) returns the same answer because t …
