Question

I have this for loop below:

for Vsb = 0:1:5
    Vtn = Vto+y*(sqrt(SurfPot + Vsb) + sqrt(SurfPot));
end

I want to plot Vtn vs Vsb for all the values of Vsb. I was trying to use the plot function but it does not seem to work.

Answer 1

the Vtn variable should be an array with 6 elements.

Vtn=[];
for Vsb = 0:1:5
    Vtn(Vsb) = Vto+y*(sqrt(SurfPot + Vsb) + sqrt(SurfPot));
end

then just plot the Vtn as a function of Vsb with the following

figure 
plot(0:5,Vtn,'*r');
