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);
