How do I input a time dependent variable from one function to fsolve function equations?

function F = A_U_G(x)
a = 2360000000;
b = 1610000000;
c = 700000;
d = 4640000000;
F(1) = x(1) - (u/b) + (b*x(2)); % qAmm
F(2) = x(2) - ((u/c)*(c/(c + d))); % qUrd
F(3) = x(3) - (u/Yd) - (x(1)*t); % qGln
end
Above is the fsolve function
x0 = [0,0,0];
x = fsolve('A_U_G',x0);
qA = x(1);
qU = x(2);
qG = x(3);
Above is the call
Now in the same function where call is made for fsolve function lies variable u, t that changes with time after each iteration.
And I want them to also change their values in function F. So, what changes need to be done?

u = randn();
x0 = [0,0,0];
x = fsolve( @(x) A_U_G(x,u), x0);
qA = x(1);
qU = x(2);
qG = x(3);
function F = A_U_G(x, u)
a = 2360000000;
b = 1610000000;
c = 700000;
d = 4640000000;
F(1) = x(1) - (u/b) + (b*x(2)); % qAmm
F(2) = x(2) - ((u/c)*(c/(c + d))); % qUrd
F(3) = x(3) - (u/Yd) - (x(1)*t); % qGln
end
