Defining a symbolic function using the "diff" command

I have a function, say

Function=@ (x) x^2

I want to differentiate this function using the Diff command:

diff(Function,x,1)

and then save the output derivative function as a new function called FunctionDerv

so it will be the same as saying:

FunctionDerv= @ (x) 2x

Function=@ (x) x^2 would be an anonymous function, not a symbolic function. None the less, you could use

syms x
sym_Function = Function(x);
sym_FunctionDerv = diff(sym_Function, x);
FunctionDerv = matlabFunction(sym_FunctionDerv);
