How to generate a loop for the problem mentioned in the context

Dear, scholars,

Anybody can help me with writing a decent code for finding the below equation:

I can write the code for the second coefficient of numerator (I mean the following part):

But I can not extend it to the whole equation,

Any ideas?

I attach my code for the second part:

clc
clear all
close all 
 
we = linspace(0,100,101);
gh = [1 3 5]; 
w = [21 39 88];

for i = 1:3
    for j = 1:length(we)
        a(i,j) = gh(i) * we(j);
        C(i,j) = (1/12)+1i*we(j);
        x(i,j) = 12*gh(i);
        s3(i,j) = 1i*gh(i)*we(j);
        s2(i,j) = w(i)^2 - we(j)^2+1i*w(i);
        s1(i,j) = 1i*gh(i)*we(j);
        v2(i,j) = s3(i,j)/s2(i,j)+C(i,j);
        v1(i,j) = s1(i,j)/s2(i,j);
        v(i,j) = abs(v1(i,j)/v2(i,j))
        d = log10(sum(v))
        d1 = sum(v);
        end
end
