Im using the fsolve function inside a loop and there is an integer inside the fsolve function that will change the solution of the fsolve, i want to increment that number each time the loop is conducted, i defined the term in global and gave it a value of 1 intially, then i tried using A=A+1 inside the loop but the fsolve gave me the final answer only to that equation and i tried putting the A=A+1 inside the function but it gave me an error.

I never tried with global variables but, in your case, I would recommend you to set your A has an input. What I understand, all variables which are not inputs of the function_handle are set as constant in the function_handle when you define it (but I could be wrong). So I would recommand to define your function handle as:
A = 1;
f = @(in1, in2, A) you_function(in1, in2, A);
while your_condition
f(in1, in2, A);
A = A + 1;
end

I don't have the optimization toolbox, so I cannot test it, but it should work like that (only the necessary code is shown:
global U Lg L2 L3 L4 L1 Th1 Th2
...
x0 = [deg2rad(145), deg2rad(20)];
x = fsolve(@(x) myfunc(x, A),x0);
...
function F = myfunc(X, A)
global U Lg
thA = X(1);
th2 = X(2);
F(1) = real( U*exp(1i*th2)-A*exp(1i*thA)-Lg );
F(2) = imag( U*exp(1i*th2)-A*exp(1i*thA)-Lg );
end
