matlab - Use derivative of function directly as an anonymous function -

i ask, if possible create anonymous function directly return value after using diff function? without copy text console , add manually anonymous function.

eg.

xy @(x)=diff(x^2,x); 

and using afterwards as: xy(3) , on.

you can use symfun symbolic function:

syms x f(x) = x^2;    % equivalent to: f = symfun(x^2,x); df = diff(f,x) % since f symfun, df df(3) 

which returns

df(x) =  2*x   ans =  6
