I have some problem with plotting, the listing is like this:
for d=1:1:100;
p=10^(-10);
a(d)=100*(10^6)*d/(2*(10^8)*12208);
u_gb(d)=(1-p)/(1+2*a(d)*p);
x(d)=d;
end
plot(x,u_gb);
those u_gb has very small data, its between 0.999999999899181 to 0.999999999899992. if I plot it, we will see straight horizontal line in the graph. Because of that, we can't see that u_gb 's value has changed
How to make this line more tilted or oblique, so that we can see that the data of u_gb is changed

try plot(x,1-u_gb,'.k');

It may help to make the data points visible in the graph.
plot(x,u_gb,'.-')

Have you tried just adjusting the y-axis scale?

yes, but still, it did't change the graph
