I want to generate the derivative of y w.r.t x from this plot. Is there a function in MATLAB which can do this ? TIA ...

To find the derivative of g for a given value of x , substitute x for the value using subs and return a numerical value using vpa . Find the derivative of g at ...

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

But I wish to do it automatically, without typing the computed derivative in Matlab everytime. I actually tried several times with fzero but it never worked...

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.

Aug 23, 2021 · MATLAB allows users to calculate the derivative of a function using diff() method. Different syntax of diff() method are: f’ = diff(f) f’ = diff(f, a) f’ = diff(f, b, 2) f’ = diff(f) It returns the derivative of function f(x) wrt variable x.
