Dirac Comb as a function of x

Hi,

I am having trouble creating a function of a Dirac comb of unit amplitude of 1. It should be a function of x.

I keep seeing codes of plotting a non-moving multiple Dirac combs on one plot using Matlab function "stem", but I only need one Dirac comb that moves to the right on one plot, using Matlab function "plot".

Below is an example of how it probably should look like. I have successfully coded up a Gaussian function that can move on one plot using Matlab function "plot" and it's a function of varepsilon and x. However, for Dirac comb, I need it as a function of x only.

function [alpha] = gaussian(varepsilon, x)

for i = 1:numel(x)

alpha(i) = (1/(varepsilon*sqrt(2*pi)))*exp(-x(i)^2/(2*varepsilon^2));

end

I have checked this link already, but I am having trouble understanding how to convert that code in that link to my format of code.
