This MATLAB function calculates differences between adjacent elements of X ... first derivative Z = diff(Y)/h; % second derivative plot(X(:,1:length(Y)),Y ...

Df = diff( f , var ) differentiates f with respect to the differentiation parameter var .

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.

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.
