Numerical integration. Integral depends on its previous path.

I would like to solve numerically an integral than depends on its previous path. Integral 7.14 from the attached file.

Are this kind of integrals solved with such loops?

Thank you.

z = 0:1/1000:10^-2
dz = z(2)-z(1); %integration step
sigma = 1;
q=0; %Integral value at z=0
for rr = 1:length(z)
fun = @(z) sigma*((10^4-exp(q))/((10^4+exp(q))));
q = integral(fun,0,x(rr),'ArrayValued',true);
end
q
