alternative of inline function

How can i use anonymous function instead of inline?

For example, I introduced a function f=@(x) x^2-2x.

Now, I want to, derivative f(x) and store it in function g(x). and find g(a) where a is a constant ie a=5.

If you want a derivative, why are you using a function handle? Using symbolic toolbox would be simpler:

syms x
f = x^2-2*x

f = 

g = diff(f)

g = 

subs(g,x,5)

ans =
