Let F be your initial function of time (as an example, let's say F(t)=t^2) and G be the approximation function (in this example let's say G(t)=sin(t)). Then you need to define the square difference function as a function handle: fh=@(t)(t.^2-sin(t)).^2 and you get the integral (meaning your error) with E=quad(fh,0,T).
