Finding difference of two components and averaged over time

I have three systems, see below. I need to compute the silmulations for different values ​​of g which is the coupling strength. Then for every value of g, i need to have a value of the difference. Then taking this difference and average over time. Can someone assist in this problem please

For intsance, I should be able to compare two components from either the first and second equation or the second and third equation and average over time

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);

sigma * (x (8) - x (7)) - g * (x (7) -x (1));

x (7) * (rho-x (9)) - x (8);

x (7) * x (8) -beta * x (9);

];

end

a = 0.2; b = 0.2; c = 5.7; sigma = 16; beta = 4; rho = 45.92
