MATLAB - Differential. MATLAB 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.
Oct 15, 2014 · I have the following anonymous function: f = @(x)x^2+2*x+1 I'm using this so that I use it in the following way: f(0) = 1 But what if I want to find the derivative of such a function while still keeping it's anonymous function capability? I've tried doing the following but it doesn't work: f1 = @(x)diff(f(x)) but this just returns []
May 13, 2013 · Accepted Answer: Sean de Wolski. I want to differentiate a function f and the calculate the derivative of f at value of x. How can I do that? for example: syms x. f=@ (x) x^3+3*x+1; g=diff (f (x)) Preferably I would like to create a function handle of the derivative and then calculate the derivative at x.
Apr 24, 2021 · Answered: Konstantin Ninidze on 24 Apr 2021. Hello Experts, I have the following function: >>f = @ (x) x^2-1. I want to find a function that will do differentiation: g = f' = 2*x so that g will be anonymous too and it will be possible to evaluate for example: g (5) = 10. Please help me,
If you differentiate an expression or function containing abs or sign, ensure that the arguments are real values. For complex arguments of abs and sign, the diff function formally computes the derivative, but this result is not generally valid because abs and sign are not differentiable over complex numbers.
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 ...
Differentiate symbolic expressions and functions. If you do not specify a variable to differentiate with respect to, MATLAB chooses a default variable.

Anonymous functions allow you to define a function without creating a program file, as long as the function consists of a single statement. A common application of anonymous functions is to define a mathematical expression, and then evaluate that expression over a range of values using a MATLAB® function function , i.e., a function that accepts a function handle as an input.
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.
