Green's Function Solution in Matlab

I wrote a code for stationary temperature distribution which is;
f = 0.09;
b = 0.0044;
q = 3.73e-9;
L = 1;
Tw = 250;
Tam = 27;
syms c x g
T = 2*c*cosh(x*((f-b*g)/q)^0.5)+g/(f-b*q);
c = solve(subs(T,'x',L/2)==0,c);
z = simplify(int(subs(T,'c',c),x,-L/2,L/2));
g = solve(z==L*(Tw-Tam),g)
Now I try to use perturbation method and find T1 temperature distribution. My equation is;
And my prof. say that can be solved by Green's function G(x,y), where the G(x,y) is soluton of;
G(L/2)=0 , G(-L/2)=0
if I can find the G(x,y), I will get the solution of T1.
Can anyone help me please?
Thank you for everything

The person who asked this question has some (slow) sample code that will solve Green's function.

clear all
syms x y
N = input('the value of N = ');
M = input('M=')
x1=input('limit of x');
x2=input(' x u');
y1=input('limit of y');
y2=input('limit of y up');

Please add comments explaining how this implements Green's function.
