Plot Polynomial graphing problem
显示 更早的评论
I don't know how to plot this equation on matlab.
A = 5.00e-30;
B = 8.00e-121;
r = 0.1:0.1:4;
V = (-A./r)+(B./r.^10);
plot(r,V)
I don't get any error. I don't know why i get a wrong graph.

What is it supposed to look like?
What function do you want to plot?

You're plotting an equation that is nothing at all like the equation for the desired graph given in http://en.wikipedia.org/wiki/Lennard-Jones_potential so why do you think you should get the same curve shape?

Your expression for ‘V’ does not closely match the Lennard-Jones potential AB-form. That suggests you should have an exponent for ‘r’ that is greater than 1 in your ‘A’ term, and that you should not negate the ‘A’ term.
Since I do not know what you are doing, I will leave that to you to sort out.
