This is very nearly the same code as you have presented before, and it has the same answer as before: it does produce a plot, and that plot contains exactly one point. Look at your code again: your code contains no loops and contains no vectors, so every variable in it is going to be scalar.

I would ask the same questions here as I have asked you before with regards to your very similar code, which you have not answered. See http://www.mathworks.co.uk/matlabcentral/answers/109098-may-i-know-what-is-wrong-with-the-program-as-it-is-not-showing-any-output#comment_184744

Your current code has lateralstraggle=2*10^-9 so should we assume that the unit is meters, and thus that 5 nm would correspond to 5*10^(-9) ? What increment are you hoping for?
