code to find difference between dynamical systems

how do i write the code to find the difference of two dynamical equation please. For instance i need to find the change or delta between x (1) and x (4) see my equation below

function dx = attractor (x, a, b, c, sigma, beta, rho, g)

dx = [

- (x (2) + x (3));

x (1) + a * x (2);

b + x (3) * (x (1) -c);

sigma * (x (5) - x (4)) - g * (x (4) -x (1));

x (4) * (rho-x (6)) - x (5);

x (4) * x (5) -beta * x (6);

end

Do you wanto find the difference between x(1) and x(4) or dx(1) and dx(4) in either of the cases a simple:

del_x=abs(dx(1)-dx(4));

should do the trick.

Please elaborate on your problem.

hello, thank you for this answer. I needed to take the difference over time and space. I have gotten it
